Postgres-XL 9.5 R1 Beta2 Announced!

The Postgres-XL community is pleased to announce the 2nd Beta release of
Postgres-XL 9.5 R1.

Postgres-XL is a massively parallel database built on top of, and very
closely compatible with PostgreSQL 9.5 and its set of advanced features.
Postgres-XL is fully open source and many parts of it will feed back
directly or indirectly into later releases of PostgreSQL, as we begin to
move towards a fully parallel sharded version of core PostgreSQL.

Some of the major enhancements that went into the Beta2 release are:

* Improve handling of Append and MergeAppend plans. They are now pushed
down to the datanodes whenever possible.
* Add support for 3-stage aggregation for json_agg() aggregate, thus
improving performance for the aggregate handling.
* Add support for checking status of a coordinator or datanode slave
without requiring it to be started as a Hot Standby.
* Fix a bug in parameter handling, which was causing certain errors in
plpgsql procedure execution.
* Correctly include the string terminator in calculating GID size, without
which the GID will look corrupted and unusable after a crash recovery.
* Fix handling of binary data transfer for JDBC as well as libpq protocols.
* Add support for process level control for overriding log levels for elog
messages.
