[Pgpool-committers] pgpool - pgpool-II: Fixed kind mismatch error when deadlock error

[User Y-asaba]

Log Message:
-----------
Fixed kind mismatch error when deadlock error occured.
The problem is the following senario.

  A: BEGIN:
  B: BEGIN;
  A: LOCK TABLE t1 IN SHARE ROW EXCLUSIVE MODE;
  B: LOCK TABLE t2 IN SHARE ROW EXCLUSIVE MODE;
  A: LOCK TABLE t2 IN SHARE ROW EXCLUSIVE MODE;
  B: LOCK TABLE t1 IN SHARE ROW EXCLUSIVE MODE;

Transaction "A" aborts on master node, but it completes on another
nodes. It causes wrong failover.

So pgpool checks deadlock error(code == '40P01') and sends error query
to another nodes.
