pg_class.oid at 4B

[Radoslav Nedyalkov <rnedyalkov@xxxxxxxxx>]

Hello all,

We have a busy database that has oid increasing with 50-100M  per month.

There is no oid type across user attributes anywhere nor user tables with oids;

Not sure where this generation comes from. If you can hint me, it would be great.

Also what happens when pg_class.oid reaches 4B.

pg_class itself is ~40K.

Thank you very much,

Rado
