Re: oids

All of my tables are without oids.

I have an application in which I drop, then recreate a table (to reset
serial numbers) and with an update on the new information I get an error
about a specific oid missing.

Any thoughts would be appreciated.

Yes and no.  WITHOUT OIDS specifies that you don't want each row to
get its own oid.  You will often here of "a table's oid" and what
that is is the oid of the pg_class entry for that table.  The default
when creating tables is WITHOUT OIDS and you should leave it that way.
