[pgpool-committers: 1855] pgpool: Fix backend error of prepared statement including now() via JDB

[Muhammad Usama]

Fix backend error of prepared statement including now() via JDBC in replication mode

With JDBC, when a prepared statement is executed more than PreparedThreshold times,
the statement is named, and pgpool rewrites now() to parameter in replication mode.
Hence, rewritten query has additonal parameter, so Bind message also should inclued
additional parameter format codes. However, when the number of original parameter was
one, pgpool didn't handle this. This caused a error like "incorrect binary data format
in bind parameter 2" on backend.
