New FAQ item:
<H4><A href="#4.25">4.25</A>) How do I perform queries
using multiple databases?<H4>
<P>There is no way to query any database except the current one.
Because PostgreSQL loads database-specific system catalogs, it is
uncertain how a cross-database query should even behave.</P>
<P>Of course, a client can make simultaneous connections to
different databases and merge the information that way.</P>
