Ответ на default to WITHOUT OIDS?  (Neil Conway <neilc@samurai.com>)
Список pgsql-hackers
The real question is how tables are dumped from 7.3 and below.  Does it
always explicitly specify 'WITH OIDS' for tables with OIDs?

If not, this would have little benefit for me I guess...

I still vote for the ability to drop OIDs from a table :)
