Well, strictly speaking, if they're from the same architecture, with
the same compile time options and the same major version of pgsql*
then you can. But you need to shut down the source and destination
servers while doing it.

* Note that in pgsql the first TWO numbers denote a major version, so
8.1 and 8.2 are NOT the same major version.
