324 * There is a bug in the function executor. The backend crashes while trying to
325 * execute an sql function containing an utility command (create, notify, ...).
326 * The bug is part in the planner, which returns a number of plans different

328 * in part in the function executor which assumes that all commands are normal

341 * The comparison routines for text and char data type give incorrect results

343 * perform the comparison using signed char variables all character codes

364 * User locks are handled totally on the application side as long term
