I think the complete code should be:

(user)
(open 'external-calls)
(open 'load-dynamic-externals)
(run '(load-dynamic-externals
        "/home/dca/Finances/Invest/Options/Scheme48/postgresql.so" #f #f #f))
(run '(import-lambda-definition pg_open_connection (dbname)))

That would be excellent - I've heard that often, but after all these
years with Scheme 48, I don't see the problems anymore.

PS: It seems you're working on PostgreSQL bindings.  I'm currently
working on a general DB access infrastructure with high-level queries.
Would you be interested to contribute your code?
