7.4.4 isn't going to happen. Another serious bug was found after it was wrapped
and some unofficial rpms were created. So the next release will be 7.4.5.
It should be announced shortly. (Probably within a day if no problems are
found with the wrapped version being checked out now.)

You will definitely want to upgrade to 7.4.5 from any previous 7.4.*
release as a potential data corruption problem after a crash is fixed
in this version.

The release notes are as follows (most sgml markup not removed):

<para>
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.

<itemizedlist>
<listitem><para>Prevent possible loss of committed transactions during crash</para>
<para>
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.  This is a serious bug that has existed
since <productname>PostgreSQL</productname> 7.1.
