[pgpool-committers: 5334] pgpool: Fix segmentation fault occurs when a certain Bind message is se

[Bo Peng]

Fix segmentation fault occurs when a certain Bind message is sent in native replication mode.

If the number of parameter format codes is specified to one, but the number of the original query's
parameter is zero, bind_rewrite_timestamp() will call memcpy with a negative value for size_t.
This causes segmentation fault.

Patch is provided by Yugo Nagata.
Per bug 443.
