Oops. While I was writing the previous email, Tom explained necessity of the pg_attrdef.

All the other thoughts from my previous email stand good. -- Best regards, Vitaly Burovoy -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
