disable NOTICES in psql output

How do I stop psql (PostgreSQL client) from outputting notices? e.g.

psql:schema/auth.sql:20: NOTICE: CREATE TABLE / PRIMARY KEY will create implicit index "users_pkey" for table "users"

In my opinion a program should be silent unless it has an error, or some other reason to output stuff.

Solution 1:

SET client_min_messages TO WARNING;

That could be set only for the session or made persistent with ALTER ROLE or ALTER DATABASE.

Or you could put that in your ".psqlrc".

Solution 2:

Probably the most comprehensive explanation is on Peter Eisentrauts blog entry here (Archive)

I would strongly encourage that the original blog be studied and digested but the final recommendation is something like :

PGOPTIONS='--client-min-messages=warning' psql -X -q -a -1 -v ON_ERROR_STOP=1 --pset pager=off -d mydb -f script.sql
