What some common function like pg_show():
SELECT pg_show('CLIENT_ENCODING');SELECT pg_show('SERVER_ENCODING');SELECT pg_show('DATESTYLE');
that returns same result as standard 'SHOW' command, but not as NOTICE?
A lot of code for this function can be shared with current SHOW routines.
I'm sure non-libpq clients (like JDBC) maintainers will happy with it.
