pglogical announced

2ndQuadrant is pleased to announce the availability of pglogical, the next
generation in replication systems for PostgreSQL.

pglogical offers Logical Replication as a PostgreSQL extension, which
provides the flexibility of trigger-based replication with the efficiency of
log-based replication. This ground-breaking new technology has benefits for
many key use cases:

* UPGRADE Upgrade PostgreSQL from 9.4 to 9.5, without
downtime

* SCALE OUT Copy all or a selection of database tables
to other nodes in a cluster

* AGGREGATE Accumulate changes from sharded database
servers into a Data Warehouse

* INTEGRATE Feed database changes in real-time to other
systems

* PROTECT Provide backup or high availability for
clusters, replacing earlier technologies

Existing PostgreSQL users will find the efficiency of pglogical particularly
exciting with preliminary testing demonstrating a significant increase in
transaction throughput (without lag) over other replication methods. For
example, pglogical performed up to 5 times faster than Slony and Londiste3
on OLTP workloads using pgBench.

For more details and access to binary packages for both the current stable
release PostgreSQL 9.4 and the soon to be announced PostgreSQL 9.5 version
