That's because your query is expanding to:

SELECT 'filenm' FROM beamdata GROUP BY 'filenm';

Which is probably not what you're looking for. The reason postgres is
complaining is because grouping by a constant doesn't make any sense.
Integer constants are special-cased to mean column numbers, hence the
reference to non-integer constants.

Hope this helps,
