[Pgpool-committers] pgpool - pgpool-II: Load balancing node was changed after processing

[User Y-asaba]

Log Message:
-----------
Load balancing node was changed after processing transaction.
For example,

  SELECT 1; <-- node 1
  BEGIN;
  SELECT 2; <-- node 0(master)
  END;
  SELECT 3; <-- node 0(master)

"SELECT 3" was sended to a master node, not a load balancing node.

VALID_BACKEND macro does not check node validation if
in_load_balancing is 1. So we do not use VALID_BACKEND macro to check
whether load balancing node is down.
