That comment in the FAQ seems quite out-of-date.
What will actually happen is that the OID generator will wrap around.
This will not bother Postgres particularly, but you may start having
occasional transaction failures due to duplicate OIDs --- for example,
I believe lo_create will fail if the OID it selects already exists in
pg_largeobject.
