Hello!
Please take a look at the patch.
Thanks.

It's most useful for making readable queries generated by ORMs such as
Hibernate. But in general, external processing can go far beyond
formatting task.
I've implemented this feature quick-and-dirty long ago. Finally I made
myself clean it up, now it looks better, so please consider a patch.
Tested on Windows 7 and Ubuntu 14.04.
Changes:
* added new setting, ExtFormatCmd, "External formatting utility" in
Options dialogue
* added menu item "Edit - Format - External Format" in
Query editor
* class sysProcess supports UTF-8 and can pass STDIN for a process.
Suggested use scenario:
1. Download and install some SQL formatting utility.
2. Tell pgAdmin where it resides:
File - Options - Query Editor: External formatting utility.
3. Open Query editor. Select a text block to format and press
Ctrl-Shift-F. With no selection the whole text gets formatted.
In case of non-zero exit code, STDERR will be shown in status bar.
Requirements for external formatting utility:
* Accepts a STDIN stream and writes result to STDOUT
* Finishes in less than 3 seconds
* Exits with code 0 on success
Support for UTF-8 multibyte characters is preferable.
To see whether it works well, a test can be done:
C:\> type in.sql |some_formatter >out.sql
C:\> echo %ERRORLEVEL%
or
user@linux:~$ cat in.sql |some_formatter >out.sql
user@linux:~$ echo $?
There are few available utilities depending on platform:
* Free SQL Formatter (Linux, Windows, Mac OS X(?))
http://fsqlf.sourceforge.net/
* Poor Man's T-SQL Formatter (Windows)

Also it is possible to make a wrapper script for numerous online
formatting services, but it's less secure and less reliable.
Fsqlf is FOSS and seems promising. I think of extending it for
PosgreSQL-specific SQL syntax and probably even PL/pgSQL.
