It's not overly pretty, but also not that bad. I was wondering whether
we could make psql_command accept multiple statements (annoying due to
argument passing - although I guess we could switch to using numeric
references to arguments), use putenv to put client_min_messages into
PGOPTIONS (to finnicky to remove again), have psql_command pass the
command to psql via stdin (more code needed for pipe setup). So I think
we can just go with what you're proposing. Although I also could just go
with always supressing notices in psql_command().
