Comments and datestyle

Hi,

Q1: Is there any way I can get the comments, I wrote on each colomn when I
created the table?

Q2: I have a datestyle on the database witch is ISO, EUROPEAN (02-12-2002).
Then I have a coloumn with the type Date. When I query the table, the format
written on my homepage is ISO, US (2002-12-02). How can I convert the
datestyle on the homepage, so it matches the database datestyle?

Well, there is no mechanism in Postgres for specifying comments during table
creation, but some apps emulate this by calling the COMMENT command as
applicable. In any case, to retrieve table comments:

SELECT pg_description.description FROM pg_class, pg_description WHERE
pg_class.relname = 'table_name' AND pg_class.oid = pg_description.classoid

DATESTYLE is a run-time configuration variable, and is only valid for the
connected session, which isn't reliable in an HTTP environment. You are
better off using to_char() to format your date output.

Graphical representation of database schema

Is there any tool to semi-automatically generate documentation and/or
graphics for a database schema? Sort of javadoc for postgresql instead of
Java.

Thanks
