Postico is under active development. Leave your email adress and I'll tell you about new features as soon as they're ready.

What is Postico? A modern PostgreSQL client for OS X. Postico provides an easy to use interface, making Postgres more accessible for newcomers and specialists alike. Postico will look familiar to anyone who has used a Mac before. Just connect to a database and begin working with tables and views. Postico makes PostgreSQL approachable. PostgreSQL is an absurdly powerful database, but there's no reason why using it should require an advanced degree in relational theory.

Postico will look familiar to anyone who has used a Mac before. Just connect to a database and begin working with tables and views. Start with the basics and learn about advanced features of PostgreSQL as you go along.

Postico is an intuitive app for looking at data. Filter rows, sort them, rearrange columns. You can examine long text or images conveniently in the sidebar. Even related rows from referenced tables are shown.

Edit rows directly, or use the sidebar — a great choice for long text. You can even change multiple rows at once. Batch saving (with SQL preview) lets you commit changes to multiple rows in a single transaction.

Add and remove columns, rename them, change types. Modify tables and views without having to remember the ALTER TABLE syntax.

The unified structure editor displays everything you need to know about a table. Comments and constraints are shown right next to the columns.

When you need hard questions answered, PostgreSQL offers many advanced tools for data analysis: Common table expressions, recursive queries, filter aggregates, window functions.

To access these tools, Postico sports a powerful query view with support for multiple result sets. The editor has all the standard features you expect, like syntax highlighting and automatic indentation.

Native Experience
Native Cocoa controls ensure consistency. Keyboard shortcuts follow platform conventions. Commands like undo/redo or copy/paste work just as you'd expect. And of course, Postico plays nice with other apps and services you use every day.

Vibrant Design
Postico was designed from the ground up with Apple's modern design language in mind. Its high resolution artwork looks great on Retina displays.

Secure out of the box
Postico uses industry standard encryption: both SSL and SSH can be used for secure connections. Server certificates are always validated. Passwords are stored safely in the system keychain. A warning is shown if the server requests a plain text connection.

Dependable Customer Support
When you have a question, you can contact the developers directly — We personally answer all customer emails. You don't have to deal with outsourced support agents, and you'll never get a canned response.

A Companion to Postgres.app
Postgres.app is the fastest way to run a PostgreSQL server locally. Since Postico is made by the maintainer of Postgres.app, the two apps co-operate perfectly.

Optimized for small displays
A slim toolbar conserves vertical screen estate. The sidebars can be hidden to show more of your data. And if you don't want to waste a single pixel, switch to full screen mode.

• Announcements of major new features
• Notification when security issues come up
• 3-4 emails per year

Which versions of PostgreSQL are supported?
Postico supports PostgreSQL 8.0 and later. We run automated tests to ensure compatibility with PostgreSQL 8.4, 9.x, 10, 11, and 12. Postico also supports database systems derived from PostgreSQL like Amazon Redshift or Greenplum, and systems that use the PostgreSQL protocol like CockroachDB.

What are the limitations of the free trial?

• At most 5 connection favorites
• Only a single window per connection
• Table filters are disabled
• There is no time limit — use the trial as long as you want!

Should I buy Postico on the Mac App Store or from your website?
It's your choice! Many customers prefer the convenience of the App Store. You have all licenses in one place, and your software is automatically updated. The store on my website (operated by Fastspring) has better support for business customers. Also, Fastspring charges a lower commission, so the version on my website is slightly cheaper.

I bought a shiny new Macbook! How can I transfer my license?
If you use migration assistant, your license will be transferred automatically. Otherwise open Postico, go to the 'Help' menu, select 'License Information', then click the 'Show License File' button. Copy that license file to your new computer, and on the new computer drag it on the Postico icon to activate.

Do you have an issue tracker for bug reports and feature requests?
I've set up a Github repository for public feature requests and bug reports. But of course you can also reach out privately via email: postico@eggerapps.at.
If you need a bug fixed quickly, consider following the best practices for bug reporting.

The character set support in PostgreSQL allows you to store text in a variety of character sets (also called encodings), including single-byte character sets such as the ISO 8859 series and multiple-byte character sets such as EUC (Extended Unix Code), UTF-8, and Mule internal code. Undistracted 1 42 download free. All supported character sets can be used transparently by clients, but a few are not supported for use within the server (that is, as a server-side encoding). The default character set is selected while initializing your PostgreSQL database cluster using initdb. It can be overridden when you create a database, so you can have multiple databases each with a different character set.

An important restriction, however, is that each database's character set must be compatible with the database's LC_CTYPE (character classification) and LC_COLLATE (string sort order) locale settings. For C or POSIX locale, any character set is allowed, but for other libc-provided locales there is only one character set that will work correctly. (On Windows, however, UTF-8 encoding can be used with any locale.) If you have ICU support configured, ICU-provided locales can be used with most but not all server-side encodings.

Dash 4 6 3. Table 23.1 shows the character sets available for use in PostgreSQL.

Table 23.1. PostgreSQL Character Sets

Not all client APIs support all the listed character sets. For example, the PostgreSQL JDBC driver does not support MULE_INTERNAL, LATIN6, LATIN8, and LATIN10.

Postico 1 3 2 – A Modern Postgresql Clients

The SQL_ASCII setting behaves considerably differently from the other settings. When the server character set is SQL_ASCII, the server interprets byte values 0–127 according to the ASCII standard, while byte values 128–255 are taken as uninterpreted characters. No encoding conversion will be done when the setting is SQL_ASCII. Thus, this setting is not so much a declaration that a specific encoding is in use, as a declaration of ignorance about the encoding. In most cases, if you are working with any non-ASCII data, it is unwise to use the SQL_ASCII setting because PostgreSQL will be unable to help you by converting or validating non-ASCII characters.

initdb defines the default character set (encoding) for a PostgreSQL cluster. For example,

Postico 1 3 2 – A Modern Postgresql Client Documentation

sets the default character set to EUC_JP (Extended Unix Code for Japanese). You can use --encoding instead of -E if you prefer longer option strings. If no -E or --encoding option is given, initdb attempts to determine the appropriate encoding to use based on the specified or default locale.

You can specify a non-default encoding at database creation time, provided that the encoding is compatible with the selected locale:

This will create a database named korean that uses the character set EUC_KR, and locale ko_KR. Another way to accomplish this is to use this SQL command:

Notice that the above commands specify copying the template0 database. When copying any other database, the encoding and locale settings cannot be changed from those of the source database, because that might result in corrupt data. For more information see Section 22.3.

The encoding for a database is stored in the system catalog pg_database. You can see it by using the psql-l option or the l command.

Important

On most modern operating systems, PostgreSQL can determine which character set is implied by the LC_CTYPE setting, and it will enforce that only the matching database encoding is used. On older systems it is your responsibility to ensure that you use the encoding expected by the locale you have selected. A mistake in this area is likely to lead to strange behavior of locale-dependent operations such as sorting.

PostgreSQL will allow superusers to create databases with SQL_ASCII encoding even when LC_CTYPE is not C or POSIX. As noted above, SQL_ASCII does not enforce that the data stored in the database has any particular encoding, and so this choice poses risks of locale-dependent misbehavior. Using this combination of settings is deprecated and may someday be forbidden altogether.

Postico 1 3 2 – A Modern Postgresql Client Server

PostgreSQL supports automatic character set conversion between server and client for many combinations of character sets (Section 23.3.4 shows which ones).

To enable automatic character set conversion, you have to tell PostgreSQL the character set (encoding) you would like to use in the client. There are several ways to accomplish this:

• Using the encoding command in psql. encoding allows you to change client encoding on the fly. For example, to change the encoding to SJIS, type:

• libpq (Section 33.10) has functions to control the client encoding.

• Using SET client_encoding TO. Setting the client encoding can be done with this SQL command:

  Also you can use the standard SQL syntax SET NAMES for this purpose:

  To query the current client encoding:

  To return to the default encoding:

• Using PGCLIENTENCODING. If the environment variable PGCLIENTENCODING is defined in the client's environment, that client encoding is automatically selected when a connection to the server is made. (This can subsequently be overridden using any of the other methods mentioned above.)

• Using the configuration variable client_encoding. If the client_encoding variable is set, that client encoding is automatically selected when a connection to the server is made. (This can subsequently be overridden using any of the other methods mentioned above.)

If the conversion of a particular character is not possible — suppose you chose EUC_JP for the server and LATIN1 for the client, and some Japanese characters are returned that do not have a representation in LATIN1 — an error is reported.

If the client character set is defined as SQL_ASCII, encoding conversion is disabled, regardless of the server's character set. (However, if the server's character set is not SQL_ASCII, the server will still check that incoming data is valid for that encoding; so the net effect is as though the client character set were the same as the server's.) Just as for the server, use of SQL_ASCII is unwise unless you are working with all-ASCII data.

PostgreSQL allows conversion between any two character sets for which a conversion function is listed in the pg_conversion system catalog. PostgreSQL comes with some predefined conversions, as summarized in Table 23.2 and shown in more detail in Table 23.3. You can create a new conversion using the SQL command CREATE CONVERSION. (To be used for automatic client/server conversions, a conversion must be marked as 'default' for its character set pair.)
