Fix rare failure to invalidate relation cache init file (Tom Lane)
</para>
<para>
With just the wrong timing of concurrent activity, a <command>VACUUM
FULL</> on a system catalog might fail to update the <quote>init file</>
that's used to avoid cache-loading work for new sessions. This would
result in later sessions being unable to access that catalog at all.
This is a very ancient bug, but it's so hard to trigger that no
reproducible case had been seen until recently.

<para>
Avoid deadlock between incoming sessions and <literal>CREATE/DROP
DATABASE</> (Tom Lane)
</para>
<para>
A new session starting in a database that is the target of
a <command>DROP DATABASE</> command, or is the template for
a <command>CREATE DATABASE</> command, could cause the command to wait
for five seconds and then fail, even if the new session would have
exited before that.
