pg_catalog table does not exist.
This is a solution for PostgreSQL 8.4.
If you know of a way I can get all primary key fields or have a query
that will work in 8.4, please help. I have done a lot of research and
cannot find a simple way.

How would I go about this? I want to hard code the number of tables
and be able to iterate through some structure to get the table name
and the primary key field.
that info is all in pg_catalog... pg_tables is a view of all tables...
if you left join that with pg_index qualified by indisprimary, you'll
probably get what you need. you'll probably need to join pg_namespace
to get the index name from its oid.
