dump 7.3 into 7.2?

You will have to do some manual hacking on the schema declarations,
almost certainly. I'd recommend dumping the schema and data separately
so that the schema file is small enough to edit manageably. Once you
have a schema that loads into the 7.2 database, the data should follow
easily.

probably be more profitably invested on updating the 7.2 installation
to 7.3. See the 7.3 release notes for reasons why.

Tom,

Do you know if it is possible to upgrade postgresql on a RAQ4?

In case anyone wants to know (or find out later searching the archives), I
was able to do this with minimal effort.

Here's what worked for me:

1) Dump the 7.3 DB using the --inserts clause.

2) Do a search and replace in the dumpfile, replacing
"pg_catalag.setval" with just "setval".

3) Comment out all the lines at the beginning that create the
databases themselves.

4) In 7.2, create the databases you need via the command line.

5) Dump the file back into 7.2.
