[Pgpool-committers] pgpool - pgpool-II: Change wait_for_query_response() so that it sends

[User T-ishii]

Log Message:
-----------
Change wait_for_query_response() so that it sends NOTICE message to
frontend periodically. It appears that pgpool-II 2.2.3 unconditionaly
sends param packet to client even it uses version 2 protocol, which
is apparentlt wrong. Also tweak checking period from 1 second to
30 seconds since 1 second seems too aggressive.
Note that you need to edit pool_process_query.c to define
SEND_NOTICE_ON_PROTO2 around line 879 to enable this feature in
version 2 protocol.
