pgsql: Add a bunch of new error location reports to parse-analysis error

Log Message:
-----------
Add a bunch of new error location reports to parse-analysis error messages.
There are still some weak spots around JOIN USING and relation alias lists,
but most errors reported within backend/parser/ now have locations.
