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.
