actually I don't know what PSPP is.

It is possible to install more PostgreSQL versions side by side using a different port for
each. With initdb you have to give the data directory for PG. There, all the necessary
data for the cluster are saved. Ubuntu is creating for each PostgreSQL version an own
folder as shown below.

In Debian based OS you will find all needed files in the following directoy's:

# home directory of user postgres (main is the so called data directory):
/var/lib/postgresql/8.3/main/

base
global
pg_clog
pg_multixact
pg_subtrans
pg_tblspc
pg_twophase
PG_VERSION
pg_xlog
postmaster.opts
postmaster.pid

The data for each database are located in a subfolder of "base" named with its OID. I
suppose this will be the folder you need or - dependent to your aqpplication - the main
directory shown above.

# configuration files:
/etc/postgresql/8.3/main/


# additional stuff:
/usr/share/postgresql/8.3/

Hope this helps ...
