[pgpool-committers: 74] pgpool: Fix pool_add_table_oid_map() so that it does not read oid map f

[Tatsuo Ishii]

Fix pool_add_table_oid_map() so that it does not read oid map file to
make sure that same md5 key has not been already registered. This is
not necessary because:
1) If the same key has been already registered, the data should be
   taken from the cache.
2) Registering same keys is not harmful.

This change significantly enhances the performance.
