/usr/share/doc/moodle/README.Debian contains a QUICKSTART/DATABASE CREATION section that's pertinent, but it's valid to at least depend on pg*.

Closes: 371834 372713 381194 386476 387177
Changes:
 moodle (1.6.2-1ubuntu1) edgy; urgency=low
 .
   * Merge from Debian unstable. The following Ubuntu changes remain:
     - debian/control:
       + Apply patch from Ubuntu #59472 to use php5
         (Closes Ubuntu: #59472),
       + Add postgresql-client-8.1 to Depends (Closes Ubuntu: #51813),
       + Update Recommends alternate to postgresql-8.1,
     - debian/templates: Ensure the default corresponds to the install-
       time dependencies (apache2) so we can avoid the mess that was
       worked around in dapper-security.
 .
 moodle (1.6.2-1) unstable; urgency=low

   * New upstream release, closes: #387177

 .
 moodle (1.6.1+20060825-1) unstable; urgency=low
 .
   * New upstream release
   * Moodle neither uses nor plans to use ADODB_Pager, so it's not affected by
     #360396, but include patch for it anyway, just in case somebody decides to
     use it out of the blue
