Fix sample server-start scripts to become <literal>$PGUSER</literal>
before opening <literal>$PGLOG</literal> (Noah Misch)
</para>
<para>
Previously, the postmaster log file was opened while still running as
root. The database owner could therefore mount an attack against
another system user by making <literal>$PGLOG</literal> be a symbolic
link to some other file, which would then become corrupted by appending
log messages.
</para>
<para>
By default, these scripts are not installed anywhere. Users who have
made use of them will need to manually recopy them, or apply the same
changes to their modified versions. If the
existing <literal>$PGLOG</literal> file is root-owned, it will need to
be removed or renamed out of the way before restarting the server with
the corrected script.

These functions used the result rowtype specified in the <literal>FROM

rowtype of the supplied tuple value. If it didn't, that would usually
result in a crash, though disclosure of server memory contents seems
possible as well.
