This is a back-patch of changes first applied in 8.4. The 8.3 code
was known buggy, but the new code was sufficiently different to not
want to back-patch it until it had gotten some field testing.

When reading <filename>pg_hba.conf</> and related files, do not treat
<literal>@something</> as a file inclusion request if the <literal>@</>

<para>
This prevents erratic behavior if a role or database name starts with

contains spaces, you can still do so, but you must write

the whole construct.

Add new configuration parameter <varname>ssl_renegotiation_limit</> to
control how often we do session key renegotiation for an SSL connection
(Magnus)
</para>
<para>
This can be set to zero to disable renegotiation completely, which may
be required if a broken SSL library is used. In particular, some
vendors are shipping stopgap patches for CVE-2009-3555 that cause
renegotiation attempts to fail.
