Uh, it's not API that's at issue here, and as for "not portable" I think you have failed to make that case. It is true that there are some old platforms where keepalive isn't adjustable, but I doubt that anything anyone is likely to be running mission-critical PG 9.0 on will lack it. regards, tom lane -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
