Hi,
i would like to use a statement replication for postgresql
Why?
i have read
http://www.postgresql.org/docs/8.2/interactive/high-availability.html
i want 4 synchronous databases with load balancing, so my
application has high performance and high availability.
synchronous replication <> high performance without lots of $$$$$$
Use a caching server or something like plproxy.
Very few people actually need synchronous replication, and those who
do buy Oracle's RAC (and curse it) or use DB2's offering (and also
curse it ;). For most purposes, fast asynchronous replication is good
enough.
Cheers,
David.
