Hello,
When working with RAISE statement in PL/pgSQL, I found a strange
situation with client_min_messages.
According to the documentation, client_min_messages does not include the
value 'INFO'.
Column enumval in pg_settings also does not contain this value:
=# select name, enumvals from pg_settings where name =
'client_min_messages';
name | enumvals
---------------------+---------------------------------------------------------------
client_min_messages |
{debug5,debug4,debug3,debug2,debug1,log,notice,warning,error}
But when we run RAISE INFO statement in PL/pgSQL, client receive a
message with any setting of client_min_messages, even most silent 'ERROR':
=# set client_min_messages = 'error';
SET
=# do $$begin raise info 'Hello, World!'; end;$$;
INFO: Hello, World!
DO
Moreover, this parameter can be set to 'INFO':
=# set client_min_messages = 'info';
SET
In this case the behavior does not changes from default 'NOTICE'.
Do we need to change something in the documentation?
P.S. log_min_messages contains INFO and works accordingly.
