Remove public execute privilege

from <filename>contrib/adminpack</filename>'s

<function>pg_logfile_rotate()</function> function (Stephen Frost)

</para>

<para>

<function>pg_logfile_rotate()</function> is a deprecated wrapper

for the core function <function>pg_rotate_logfile()</function>.

When that function was changed to rely on SQL privileges for access

control rather than a hard-coded superuser

check, <function>pg_logfile_rotate()</function> should have been

updated as well, but the need for this was missed. Hence,

if <filename>adminpack</filename> is installed, any user could

request a logfile rotation, creating a minor security issue.

</para>

<para>

After installing this update, administrators should

update <filename>adminpack</filename> by performing

<literal>ALTER EXTENSION adminpack UPDATE</literal> in each

database in which <filename>adminpack</filename> is installed.
