Set forth below are three regression test failures encountered on RedHat
6.0.  All involved differences between expected and actual dates.  The
actual date is the date the test was run:

If PostgreSQL failed to compile on your computer or you found a bug that
is likely to be specific to one platform then please fill out this form
and e-mail it to pgsql-ports(at)postgresql(dot)org(dot)

To report any other bug, fill out the form below and e-mail it to
pgsql-bugs(at)postgresql(dot)org(dot)

If you not only found the problem but solved it and generated a patch
then e-mail it to pgsql-patches(at)postgresql(dot)org instead.  Please use the
command "diff -c" to generate the patch.

You may also enter a bug report at http://www.postgresql.org/ instead of
e-mail-ing this form.
