Thank you John!
Do you know if there is any encryption or security or will plainly copying
the files will work? Do I need to know any db usernames and passwords, which
obviously I don't have?
The files should not be encrypted. There will be database usernames and
possibly passwords. I would assume the usual default superuser name
postgres. To get around the password see pg_hba.conf:
http://www.postgresql.org/docs/9.5/interactive/auth-pg-hba-conf.html
In particular you want the below at the top of the entries, assuming you
are connecting on from the same machine as the server:
local all all trust
The above says just trust anyone connecting over the local socket.
Assuming you get in then:
\du postgres
role name | Attributes | Member of
-----------+------------------------------------------------+-----------
postgres | Superuser, Create role, Create DB, Replication | {}
to verify you are superuser and then:
select * from pg_shadow ;
to see the users and whether they have passwords.

The vendor won't give us any way to access the machine and retrieve

was able to grab all the DB files and copy them to my Windows desktop,
where I then installed PostgreSQL 9.0 (to match the version that was
on the server) with pgAdmin III. I changed the default directory to
the folder containing the DB files using this tutorial:
https://wiki.postgresql.org/wiki/Change_the_default_PGDATA_directory_o
n_Windows
I would try installing postgres on linux, and try running it with a copy
of this data directory. skip the pgadmin thing entirely as its just
another layer of obfuscation, stick with CLI tools.
