As for the 'select @1' problem: 785 targetOid = func_select_candidate(1, &arg, candidates); 786 tup = SearchSysCacheTuple(OPRNAME, 787 PointerGetDatum(op), 788 ObjectIdGetDatum(InvalidOid), 789 ObjectIdGetDatum(*targetOid), 790 CharGetDatum('l')); (gdb) print targetOid $1 = (unsigned int *) 0x0 Ahem... dereferencing a NULL? Bad bad bad. PARSEDEBUG gives: unary_oper_get_candidates: start scan for '@' unary_oper_get_candidates: found candidate '@' for type float4 unary_oper_get_candidates: found candidate '@' for type float8 unary_oper_get_candidates: found 2 candidates func_select_candidate- candidate has 0 matches func_select_candidate- choose candidate as best match func_select_candidate- candidate has 0 matches func_select_candidate- choose candidate as possible match func_select_candidate- column #0 input type is int4 Anyone know where the error is supposed to be generated?
