Обсуждение: pgsql: Fix small oversight in recent patch to add more

Log Message:
-----------
Fix small oversight in recent patch to add more CREATE-FUNCTION-time
syntax checking to plpgsql: check_sql_expr() wasn't being called by
make_select_stmt(), so that there was no SQL syntax check for SELECT
statements.
