Sorry, I've been out of town.

The only way to do this is to copy your existing relations out to
unix files and once the new installation is up and running copy them
back in to POSTGRES relations (presumably you have the shema definition
in a file somewhere).

We realize this isn't very nice, but system catalog formats (and sometimes
tuple layout) can change from release to release.  In the future we will
be providing conversion routines (yes!, you heard it right) to convert
from release n to release n+1.  Starting with converting from version 4
to 4.1 and ever after....  (sorry, probably no 3.1 to 4!!)

Again, I've been out of touch for a while, so sorry for the delay.
