An option to not generate OIDs unless requested (on a table-by-table
basis) has been discussed. It seems like a fine near-term solution
to me. 8-byte OIDs are a longer-term solution, because they'll break
a lot of things (including clients...)

It's in the archives: after 4G transactions, your database curls up
and dies. When your pg_log starts to approach 1Gbyte (2 bits per
transaction) you'd better plan on dump/initdb/reload.
