PG 8.3 complains about this, whereas previous versions would have silently converted both operands to text and done a textual comparison ... leading to results that are highly unlikely to be sane at all, for this combination of datatypes. I'd say 8.3 just found a bug in your app for you. > [quote]PHP Warning: pg_query(): Query failed: ERROR: function > pg_catalog.btrim(bigint) does not exist at character 62 Again, this is 8.3 being more picky about implicit casts than prior versions. Why would you think btrim on an integer value would be useful, anyway? If you really want it, insert an explicit cast to text. regards, tom lane
