other types of objects, the default privileges
   granted to <literal>PUBLIC</literal> are as follows:
   <literal>CONNECT</literal> and <literal>TEMPORARY</literal> (create
   temporary tables) privileges for databases;
   <literal>EXECUTE</literal> privilege for functions and procedures; and
   <literal>USAGE</literal> privilege for languages and data types
   (including domains).
   The object owner can, of course, <command>REVOKE</command>
   both default and expressly granted privileges. (For maximum
   security, issue the <command>REVOKE</command> in the same transaction that
   creates the object; then there is no window in which another user
   can use the object.)
   Also, these default privilege settings can be overridden using the
   <xref linkend="sql-alterdefaultprivileges"/> command.
  </para>

  <para>
   <xref linkend="privilege-abbrevs-table"/> shows the one-letter
   abbreviations that are used for these privilege types in
   <firstterm><acronym>ACL</acronym></firstterm> values.
   You will see these letters in the output of the <xref linkend="app-psql"/>
   commands listed below, or when looking at <acronym>ACL</acronym> columns
   of system catalogs.
