In response to drop table if exists  ("Jason Watkins" <jason_watkins@pobox.com>)
List pgsql-sql
Alright, but what about when you're writing a long dump file with all these
sequences, functions not speaking about the tables themselves.
When I drop something I wanna make sure it out the database (but still
cannot empty the whole database before), so I have 

DROP TABLE ..., ..., ..., ...;
DROP FUNCTION ..., ..., ..., ...;
DROP SEQUENCE ..., ..., ..., ...;

If one of these were not there, the whole dump crashes and I need to restart
the process modifying the SQL file.

I'd LOVE to have a magic 'IF EXISTS' like in mySQL - make life easier
(Although I totally disrespect mySQL).
Has anyone a work around for this?

Thanks,
and yes, sorry for the late post, just looked you up guys.

Just drop the table using "DROP TABLE mytable;" and ignore the error...
I'm sure there are fancy ways of doing it by accessing system tables, but
the above works for me.
