[pgpool-committers: 6806] pgpool: Fix startup packet reading process.

[Tatsuo Ishii]

Fix startup packet reading process.

If there are parameters other than "user", "database" and
"application_name", reading startup packet resulted in failing to
extract user: "no PostgreSQL user name specified in startup
packet". This was found while a frontend was trying to speak
replication protocol by using "replication=database".
