NTT corporation is pleased to announce full page write optimization tool
which reduces PostgreSQL archive log size by replacing full page writes
with corresponding incremental logs.   Source material is available from
PgFoundry "full page write improvement" project,

http://pgfoundry.org/projects/pglesslog/.

The idea was discussed in Hackers mailing list and a flag was
introduced in PostgreSQL 8.3 to indicate XLOG records whose full page
writes can be replaced with corresponding incremental log.

We will continue to evaluate log size reduction by pglesslog and will
post the result.

Thank you;
