If you want to use DBD-Pg the first line would be - use DBI;

You don't have to get a database driver (DBD) to use the pg module
that comes with postgres.  You can use it immediately upon building
the db (if you built the interfaces along with the backend.)

If you want to use DBD, dial up CPAN and go to `modules by author'.
Look for Edmund Mergl.  Personally, I really like his DBD module.
As DBI (necessary for DBD) is much more widely documented than pg -
due to the fact that DBI is the generic part of the equation and DBD
modules are database specific - it might be easier for you.

You could try both.  ;-)
There is also ecpg - the ESQL(C) interface.

I use DBI::DBD-Pg almost exclusively these days and have lots of code
(public domain) that I'd be happy to send.

Let me know, a.u.b., if you'd like some code snippets.

Tot straks,
