[pgpool-committers: 7081] pgpool: Fix relcache query sometimes sent to other than primary.

[Tatsuo Ishii]

Fix relcache query sometimes sent to other than primary.

In streaming replication mode, relcache queries are supposed to be
sent to the primary node.  But actually they were not sent the primary
node if primary node was not the master node. Typically this could
happen when the primary is not node 0.
