- Fix "not enough space in buffer" error. (bug 499) (Tatsuo Ishii)
- The error occurred while processing error message returned from backend and the cause is that the query string in question is too big. Problem is, the buffer is in fixed size (8192 bytes). Eliminate the fixed size buffer and use palloced buffer instead. This also saves some memory copy work.
