Over the past week, we have bundled and released new versions of 7.2, 7.3 
and 7.4 to address a couple of potentially critical bugs that were 
recently identified.

For all three versions, these releases address the following:

      * Prevent possible loss of committed transactions during crash
        Due to insufficient interlocking between transaction commit and
        checkpointing, it was possible for transactions committed just
        before the most recent checkpoint to be lost, in whole or in part,
        following a database crash and restart.

Specific to 7.4, the following has also been fixed:

      * Repair possible crash during concurrent btree index insertions
        This patch fixes a rare case in which concurrent insertions into a
        btree index could result in a server panic. No permanent damage
        would result, but it's still worth a re-release. The bug does not
        exist in pre-7.4 releases.

Due to the seriousness of the first bug, as relates to data integrity, it 
is strongly recommended that administrators upgrade their database servers 
at their earliest convience.

None of these releases require a dump-n-reload in order to address the 
problems.

It should be noted that, for those looking to upgrade from a 7.4.0/7.4.1 
server to 7.4.5, that there a dump-n-reload is *recommended* (but not 
required) to address a fix introduced between 7.4.1 and 7.4.2.  Please 
refer to the 7.4.5 HISTORY file for information on how this can be 
accomplished without a dump-n-reload, as there are steps that can be 
followed for this.

Please refer to the following URL for a list of mirror sites where the new 
releases can be downloaded:

Devrim has been working n SRPMs for v7.3.7 and v7.4.5, as well as David 
Fetter has made sure that v7.4.5 is available via BitTorrent:

As always, please report any bugs to pgsql-bugs(at)postgresql(dot)org
