We have not checked for this KEYWORD for a long time now, so this
is a complete noop, and thus no PORTREVISION bump. Removing it at
this point is mostly for pedantic reasons, and partly to avoid
perpetuating this anachronism by copy and paste to future scripts.
o Fix more style bugs in debug message.
o Add internal function to postmaster which returns current replication
server.
o Add new packet handler to pgreplicate which returns cluster node
status information.
o Add check scripts for nagios. These scripts may be useful, but not
intended to officially supported by me. I'll make them as another
port when they become stable.
