Re: OID wraparound (was Re: pg_depend)

Tom mentioned what should be stored in the OID system column if no oid's
are in the table. He also mentioned that he doesn't want a
variable-length tuple header so will always have an oid system column.

What about moving the oid column out of the tuple header. This saves 4
bytes in the header in cases where there is no oid on the table.

If they ask for an OID in a table, make it the first column of a table.
Also, if they have asked for oid's on the table, odds are they want
SELECT * to show it.

Also, how about a GUC option that controls whether tables are created
with OID's by default.
