[Pgpool-committers] pgpool - pgpool-II: Fix do_error_execute_command() so that it discards

[User Kitagawa]

Log Message:
-----------
Fix do_error_execute_command() so that it discards responses
from backend until ErrorResponse received.
Note that we need to preserve non-error responses
(i.e. ReadyForQuery) and put back them using pool_unread().
Otherwise, ReadyForQuery response of DEALLOCATE. This could
happen if PHP PDO used.
