Huh? The variable will be set in any case. It should be correct for any server version we might find in the wild --- so far as I can tell from the commit history, every version supporting FE/BE protocol version 3 has sent server_version at connection start. With a pre-7.4 server, it looks like the variables would be set to "0.0.0" and "0" respectively. regards, tom lane -- Sent via pgsql-hackers mailing list (firstname.lastname@example.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
