Your virtual environment is a Python construct only. That's where
Python packages get installed, so if you don't activate it, you might
not be able to use psycopg2, but as you surmise, the database itself
is elsewhere on the system.

Ah, all owned by root. Okay! I've never actually tried this, but you
might be able to directly reassign a bunch of things:

http://www.postgresql.org/docs/9.4/static/sql-reassign-owned.html

Make sure you have a backup. Reassigning root in this way is quite
possibly a bad idea.

If there aren't too many tables, you could use ALTER TABLE:

http://www.postgresql.org/docs/9.4/static/sql-altertable.html

ALTER TABLE tablename OWNER TO archives;

But in theory, you shouldn't need to worry about owners at all - just
make sure permissions are all assigned. Which you have done. So it's
entirely possible none of this will change anything. :(

Worst case, you may need to do an SQL dump of the entire database,
then check the export, make sure ownership is correct, and reimport
into a brand new database. Tedious, but it's certain to fix the
problem.
