contrib/DBMirror (Replication).

[Steven Singer <ssinger(at)navtechinc(dot)com>]

I've attatched the replication system(an alternative to Rserv) that 
I mentioned the other day in pgsql-hackers.

I'd like it if the project can be added as a contrib project to the 7.3 
development tree(When its created).


The project contains a trigger written in C, a mirroring Perl script
and some setup SQL along with documentation.

The key features the system has are:

-Support for multiple slaves.
-Preserves transactions while mirroring.
-Per table selection of what tables get mirrored.

More details can be found in the README file.
