[Pgpool-committers] pgpool - pgpool-II: Fix asynchronous query handling.

[User Y-asaba]

Log Message:
-----------
Fix asynchronous query handling.

When ReadyForQuery message was received, pgpool set off loadbalancing
flag, internal transaction flag and so on. If client sended a Query
message before receiving the ReadyForQuery message, pgpool reported
error message.

So, we block the Query message while backend nodes process a query.
