Are you using postgresql 7.0 from an RPM?  What OS are you running on?

If you installed it via RPM then you can issue a command something like:

rpm -e postgresql-7.0.x

where x is the sub version number.  You can use

rpm -qa|grep postgres

to find out the package name on a machine that used RPM to install.

If you installed from a tarball, you can just install the new postgresql
on top of the old one.

Either way, use pg_dumpall to get a backup of your data first as you'll
need to perform an initdb and restore your old data (if you want to keep
it.)
