sql query

[Geoff Shang]

Hi,

The psql tool, like the mysql tool, are meant for database admins etc. 
They are not intended for generating output for end users.

These databases are intended for use with programming languages.  There 
are PostgreSQL libraries for pretty much any language you care to name. 
These will return results in  a programatic fashion, such as an array or 
list of dictionaries. You can examine the results in your program and 
present the output in any way you choose.

Geoff.
