We already had a report to that regard before but some more detail would be good to have. See http://archives.postgresql.org/pgsql-bugs/2009-05/msg00230.php for the previous report that got fixed here: http://archives.postgresql.org/pgsql-committers/2009-05/msg00311.php so that one will appear in the next pointrelease for 8.3. > > 2.'trim' is not supported by this version on both the platforms > > ERROR: function pg_catalog.rtrim(numeric, integer) does not exist > LINE t: ...ct col2_date,col4_int,colt_timestamp,col5_numeric,trim(trail... this is not a bug - there is no version of of trim() that works on numeric(and I'm not sure why one would want this). If you really have to do that operation you need to cast to text first. Stefan
