Slony 2.2.0 beta 5 has been released.

This beta includes the following fixes from beta 4:

    * Fixes for FAILOVER
    * Make test_slony_state-dbi.pl work with PG 9.2
    * log shipping apply trigger will apply EXECUTE SCRIPT changes
    * MOVE SET could previously pull data from the old origin with the 
wrong SYNC (Bug 299)
    * Eliminate memory leaks in slon
    * Fixes for the 2.1 -> 2.2 upgrade procedure
    * Documentation updates

This beta includes a few known regressions with EXECUTE SCRIPT (bugs 304 
and 305).  Please help us test and report any additional issues. I am 
hoping to have a release candidate in a few weeks with an official 
release before the end of September but that depends on how successful 
further testing is.


Key features of the 2.2.0 release include:

* The storage and transport and application of the slony log 
(sl_log_1/sl_log_2) has changed providing performance improvements. Data 
is now stored in a different format and the postgresql COPY protocol and 
triggers are used to replicate and apply changes to replicas.

* DDL handling with the EXECUTE SCRIPT command has changed.  The DDL is 
no longer stored as a special event in sl_event but is instead stored in 
sl_log_script and is processed as part of a SYNC event inline with data 
changes. DDL can also be specified inline

* FAILOVER has been reworked to be more reliable but not all nodes can 
be used as failover targets.

* A RESUBSCRIBE NODE command was added because the provider of a 
subscribed set can no longer be changed with the SUBSCRIBE SET command 
in some cases.  All sets from a particular origin must send data to 
receivers through the same path/forwarder nodes. This must remain  true 
during cluster reshaping.
