during parse analysis, not only errors detected in the flex/bison stages. This is per my earlier proposal. This commit includes all the basic infrastructure, but locations are only tracked and reported for errors involving column references, function calls, and operators. More could be done later but this seems like a good set to start with. I've also moved the ReportSyntaxErrorPosition logic out of psql and into libpq, which should make it available to more people --- even within psql this is an improvement because warnings weren't handled by ReportSyntaxErrorPosition.
