Just what is an OID within postgres?
Is it independant from any columns in a table? A sort of hidden builtin column? How do I use it, and in what way is it different from a SERIAL column.

Aren't OID's for individual queries? You can use the OID in triggers, etc, to reference only one row.
I could be way off here, but that's what I seem to remember.
