That was very helpful, many thanks About timestamp, I understood that as long as the DB server is the one to log times it is safe to use it without timezones?? (I am not using any of the different timezoned clients??) am i missing the point? about all_table_columns, it is just a simple view to have the table name and column name in the same view, (wasn't satisfied in pg_attribute only :), am i duplicating anything? ---------------------------(end of broadcast)--------------------------- TIP 1: subscribe and unsubscribe commands go to majordomo@xxxxxxxxxxxxxx
