This inconsistency will be gone in 8.3: regression=# select * from t1 where kod = 902; ERROR: operator does not exist: character varying = integer LINE 1: select * from t1 where kod = 902; ^ HINT: No operator matches the given name and argument type(s). You might need to add explicit type casts. regression=# regards, tom lane
