nextval, currval, either way, I would need to know the specific sequence
name. Was looking for a good way to pass a function a schema and table
and return a sequence. I got exactly what I was looking for and have
been able to build a function that will handle this for me. It's part of
a db layer class that I use with mysql and pgsql, and was using
mysql_insert_id and wanted to model a function that would return an id
like the mysql_insert_id function does. (one of the few pgsql/php
functions that doesn't exist in php natively..but does with mysql)
