I am a little stuck of a question. In fmgr.c:1698, function "InputFunctionCall" at line 1718
/* Should get null result if and only if str is NULL */ if (str == NULL) { .... .... What are we testing to be NULL here? Do we expect str to changed at line 1715 ( result = FunctionCallInvoke(&fcinfo); ) Please advice, Gevik. ---------------------------(end of broadcast)--------------------------- TIP 6: explain analyze is your friend
