[pgpool-committers: 738] pgpool: Fix pool_search_relcache() to use MASTER or MASTER_NODE_ID macr

[Tatsuo Ishii]

Fix pool_search_relcache() to use MASTER or MASTER_NODE_ID macro,
rather than REAL_MASTER_NODE_ID.  In case node 0 fail back in
streaming replication mode, pgpool does not restart child process.  So
REAL_MASTER_NODE_ID looks for node 0 con info, which is not present
until new connection to backend made. Thus referring to node con info
results in segfault. MASTER or MASTER_NODE_ID are safe in this
situation because they look at cached former master node id.
