EnterpriseDB Announces General Availability of Postgres Plus Advanced Server 9.1

BEDFORD, MA, Feb 09 (MARKET WIRE) --
EnterpriseDB, the leading worldwide provider of PostgreSQL and Oracle
compatibility products and services, today announced general availability
of Postgres Plus Advanced Server 9.1. The release features significant
performance enhancements, including the option to free even more
processing power for some applications with the industry's only
synchronous replication control on a per-transaction basis. This latest
version also speeds read performance and write scalability, enables
unlogged tables for greater performance and flexibility and expands the
Oracle-compatible feature set.

"Our newest version of Postgres Plus Advanced Server adds new, high-end
capabilities for performance, reliability, security and scalability. With
this release we are enabling our end users to accelerate the expansion of
their Postgres Plus deployments at a price point exponentially less than
the traditional proprietary databases," said Ed Boyajian, president and
CEO of EnterpriseDB. "These enhancements also give new users even more
reason to start looking at Postgres Plus as an alternative for their data
centers."

Postgres Plus Advanced Server 9.1 includes the following enterprise-class
enhancements:

-- Synchronous Replication - Provides maximum control over transaction
environments by enabling end users to activate synchronous replication
on a per-transaction basis (or per connection or per user) -- a level
of flexibility and control not available in any other database. This
ensures no data is lost should a master fail, and provides performance
gains by allowing the application or end user to select what
transactions are replicated. This process confirms a transaction has
been successfully applied to the slave server's journal before it is
committed to the master.
-- Unlogged Tables - Gives end users the option to maximize performance
by choosing 'unlogged' when creating tables, thus no write-ahead
logging (WAL) records are kept. This becomes useful when applications
must perform quickly and data loss, should the system fail, is not a
concern, such as an online store where the emphasis is on preserving
purchase data, but other information like the product reviews a
customer viewed, which can generate significantly more data, is less
critical.
-- Improved Read Management - Fundamental improvements to efficiently
handle more queries than ever before, and significantly improves
performance -- particularly on read-only workloads and on machines
with more CPUs.
-- Improved Write Scalability - Now more scalable than ever. New lock
manager code, lock avoidance techniques and shortened critical
sections allow Postgres Plus Advanced Server to more fully utilize the
resources of systems with 32 cores or more, rather than being limited
by lock contention.
-- Expanded Oracle Compatibility - Includes Virtual Private Database, a
type of fine-grained access control using row level security policies.
This feature allows a number of useful, centralized security
implementations that limit the data that end users may access.

Postgres Plus Advanced Server 9.1 is available today on Linux 32 and
64 bit platforms, Windows 32 and 64 bit platforms, HP-UX and Solaris. To
