update: Thanks for all your help, I finaly got it working - looks like I
was modifiying the wrong config file (for some reason there was a
duplicate, and I was modifying that one erk!)
I can create tables and perform SQL statements just great :),
however.. is it possible to open a connection to the database and
determine what tables are in the database already?
TIA,
Alex T

Of course. It's a query, just like any other query, but you select the data
from the system catalogs rather than your own tables. Take a look in the
documentation - the manpage for "catalogs".
The table you should query is probably pg_class.

Brilliant! worked first time. pg_class is the one!
I know that you can get the types from a database from the metadata, but I'm
wondering if there is also a way to issue to an SQL query to postgres that will
yield the same result.
