Обсуждение: psql -af > out, is possible to also have raise notice, raise info part.

hi.

test.sql content:
--------------------------------------------------------------------------------------------------
do $$
begin
  raise info 'information message %', now() ;
  raise debug 'debug message %', now();
  raise notice 'notice message %', now();
end $$;
--------------------------------------------------------------------------------------------------
psql -af test.sql > test.out

current result:
--------------------------------------------------------------------------------------------------
do $$
begin
  raise info 'information message %', now() ;
  raise notice 'notice message %', now();
end $$;
DO
--------------------------------------------------------------------------------------------------
expected result in test.out

do $$
begin
  raise info 'information message %', now() ;
  raise notice 'notice message %', now();
end $$;
INFO:  information message 2023-07-12 11:49:27.894126+08
NOTICE:  notice message 2023-07-12 11:49:27.894126+08

thanks.
I don't know that "raise" stuff goes to stderr.
To get rid of the line numbers, I use "psql -a < test.sql > test.out
2>&1 " to get the expected result.
