Does raise the further question of how psql behaves when we connect to a pre-10 server, so we have SERVER_VERSION_NUM but yet it is not set. How does this \if SERVER_VERSION_NUM < x
The if does not have expressions (yet), it just handles TRUE/ON/1 and FALSE/0/OFF.
Do we need some macro or suggested special handling?
If "SERVER_VERSION_NUM" is available in 10, then: -- exit if version < 10 (\if is ignored and \q is executed) \if false \echo "prior 10" \q \endif -- then test version through a server side expression, will work SELECT :SERVER_VERSION_NUM < 110000 AS prior_11 \gset \if :prior_11 -- version 10 \else -- version 11 or more \endif -- Fabien. -- Sent via pgsql-hackers mailing list (email@example.com) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
