Thread: pgsql: Improve error report for PL/pgSQL reserved word used as a field
Improve error report for PL/pgSQL reserved word used as a field name. The current code in resolve_column_ref (dating to commits 01f7d2990 and fe24d7816) believes that not finding a RECFIELD datum is a can't-happen case, in consequence of which I didn't spend a whole lot of time considering what to do if it did happen. But it turns out that it *can* happen if the would-be field name is a fully-reserved PL/pgSQL keyword. Change the error message to describe that situation, and add a test case demonstrating it. This might need further refinement if anyone can find other ways to trigger a failure here; but without an example it's not clear what other error to throw.
