Changelog:
Enhancements
* Add new configuration option ssl_prefer_server_ciphers. (Muhammad Usama)
Add the new setting ssl_prefer_server_ciphers to let users configure if they want client's or server's cipher order to take preference.
The default for this parameter is off, which prioritize the client's cipher order as usual. However this is just for keeping backward compatibility, and it is possible that a malicious client uses weak ciphers. For this reason we recommend to set this parameter to on at all times.
* Allow to set a client cipher list. (Tatsuo Ishii, Yugo Nagata)
For this purpose new parameter ssl_ciphers, which specifies the cipher list to be accepted by Pgpool-II, is added. This is already implemented in PostgreSQL and useful to enhance security when SSL is enabled.
Bug fixes
* Fix unnecessary fsync() to pgpool_status file. (Tatsuo Ishii)
Whenever new connections are created to PostgreSQL backend, fsync() was issued to pgpool_status file, which could generate excessive I/O in certain conditions. So reduce the chance of issuing fsync() so that it is issued only when backend status is changed.
* Doc: add more explanation to follow_master_command. (Tatsuo Ishii)
Add description how follow_master_command is executed etc.
* Doc: add note to detach_false_primary configuration parameter. (bug 469) (Tatsuo Ishii)
To use this feature, sr_check_user must be super user or in pg_monitor group.

Do not pass --without-pam to configure as it does not appear to
work correctly. It also defines USE_PAM in config.h even when it
should not be defined and the build breaks.

The PAM option is tangled up with the SSL option in a weird way.
SSL_CONFIGURE_WITH is set once before bsd.port.options.mk for
enabling SSL support and overwritten again after including
bsd.port.options.mk but only when PAM=on.
Setting options helper after this point is not really supported,
but --with-pam actually makes it to CONFIGURE_ARGS. When options
helpers are processed the results are only realized later by make(1).
SSL_CONFIGURE_WITH has been defined before including bsd.port.options.mk,
so this sort of "works".
This, however, is presumably an implementation detail and enabling
the PAM option breaks SSL support since SSL_CONFIGURE_WITH is
overwritten with a new value: CONFIGURE_ARGS only has --with-pam
left and is missing --with-openssl.
PAM support does not depend on SSL support. Just switch everything
to options helpers to fix this.

pgpool is a connection pool server for PostgreSQL. pgpool runs between
PostgreSQL's clients(front ends) and servers(back ends). A PostgreSQL client can
connect to pgpool as if it were a standard PostgreSQL server.
pgpool caches the connection to PostgreSQL server to reduce the overhead to
establish the connection to it.
