First of all, some administration can be easily performed with queries,
such as CREATE DATABASE, DROP DATABASE, CREATE LANGUAGE, etc.

To work with something like pg_dump, just open a pipe. Generally you
want to output to a file anyway. It would be odd to have something like
a pg_dump api call that dumped information out as a Java string. If
nothing else, you might not be able to store the entire string in
memory, so the interface of unix pipes is much better.
