It *is* (apologies for the hijack) too verbose but whatever context
suppressing we added doesn't work in pretty much any interesting case.
What is basically needed is for the console to honor
log_error_verbosity (which I would prefer) or a separate GUC in manage
the console logging verbosity:
set log_error_verbosity = 'terse';
SET
CREATE OR REPLACE FUNCTION Notice(_msg TEXT) RETURNS VOID AS
$$
BEGIN
RAISE NOTICE '[%] %', clock_timestamp()::timestamp(0)::text, _msg;
END;
$$ LANGUAGE PLPGSQL;
CREATE OR REPLACE FUNCTION foo() RETURNS VOID AS
$$
BEGIN
PERFORM Notice('test');
END;
$$ LANGUAGE PLPGSQL;
-- context will print
postgres=# select foo();
NOTICE: [2013-08-21 09:52:08] test
CONTEXT: SQL statement "SELECT Notice('test')"
PL/pgSQL function foo() line 4 at PERFORM
CREATE OR REPLACE FUNCTION bar() RETURNS VOID AS
$$
SELECT Notice('test');
$$ LANGUAGE SQL;
-- context will not print
postgres=# select bar();
NOTICE: [2013-08-21 09:54:55] test
-- context will print
CREATE OR REPLACE FUNCTION baz() RETURNS VOID AS
$$
select 0;
SELECT Notice('test');
$$ LANGUAGE SQL;
postgres=# select baz();
NOTICE: [2013-08-21 09:55:26] test
CONTEXT: SQL function "baz" statement 2
