slave servers. I haven't tested it very well, so use at your own risk (and I recommend against using it in production). Basically, I have a central database server that has 4 summary tables inside it replicated to a remote slave (these database tables are for my mail server authentication, so these are replicated to another server tuned for many connections, and so I don't have postgres connections opened straight to my back-end database server). Unfortunately, I also wanted to implement a replication database server for hot-backups. I realized, too late, that the replication process is pretty greedy and will try to replicate all tables marked as a "MasterAddTable". To make a long story, I made a patch to RServ.pm and Replicate that allows you to specify, on the command line, a list of tables that you want to replicate...it'll ignore all others. I haven't finished, since this has to be integrated with CleanLog for instance, but this should (and does) suffice for the moment. I have yet to test it with two slaves, but at least my mail server replication database now works (it was failing every time it tried to replicate, for a variety of reasons). Anyone have any suggestions on how to improve on this? (or, if someone more familiar with this code wants to take the ball and run with it, you're welcome to). -- Michael A Nachbaur <mike@nachbaur.com> |

PostgreSQL Database Management System ===================================== This directory contains the source code distribution of the PostgreSQL database management system. PostgreSQL is an advanced object-relational database management system that supports an extended subset of the SQL standard, including transactions, foreign keys, subqueries, triggers, user-defined types and functions. This distribution also contains several language bindings, including C, Perl, Python, and Tcl, as well as a JDBC driver. The ODBC and C++ interfaces have been moved to the PostgreSQL Projects Web Site at http://gborg.postgresql.org for separate maintenance. See the file INSTALL for instructions on how to build and install PostgreSQL. That file also lists supported operating systems and hardware platforms and contains information regarding any other software packages that are required to build or run the PostgreSQL system. Changes between all PostgreSQL releases are recorded in the file HISTORY. Copyright and license information can be found in the file COPYRIGHT. A comprehensive documentation set is included in this distribution; it can be read as described in the installation instructions. The latest version of this software may be obtained at ftp://ftp.postgresql.org/pub/. For more information look at our web site located at http://www.postgresql.org/.
