[Pgpool-committers] pgpool - pgpool-II: Enhance "kind mismatch" message.

[User T-ishii]

Log Message:
-----------
Enhance "kind mismatch" message. If kind is ERROR or NOTICE, print the
ERROR/NOTICE message to help users to find what's going on.
For this pupose, add new function pool_extract_error_message() into
pool_process_query.c.

Fix sloppy coding of detect_erorr(). Check memory allocation error,
check buffer overrun error.
