It's not hard.
You may either intercept the exception( EXCEPTION WHEN OTHER ...) so that the transaction will not be rollbacked, so
youcan easily insert into another table what you want.
But, if you want to rollback the transaction with a RAISE EXCEPTION, you just have to insert in your log table using
anothertransaction, for example with a loopback dblink.
Something like :
select setting INTO l_port FROM pg_settings WHERE name = 'port';
PERFORM * FROM dblink(
FORMAT('dbname=%s user=%s port=%s',current_database(), current_user, l_port),
FORMAT('INSERT INTO TRACE_ERROR(ernno,errmsg,errcontext) VALUES (%L,%L,%L);',l_errno,l_errmsg,l_errctx)
) AS p (ret text);
Otherwise, when you rollback, the INSERT into the error log table will be also rollbacked.
