I think the correct solution would be to document the 'dsn' parameter to
psycopg2.connect and perhaps even encourage people using it.
This pushes the trouble of parsing out and interpreting parameters to
libpq, which is good, for in the end the important thing is that libpq
sees what you want it to see.
For instance, this patch (and AFAICS vanilla psycopg2 too) does not
handle usernames with spaces in them. Instead of implementing quoting as
expected by libpq, why not just let the user use a DSN that will work
equally with psql as with any other libpq app out there?
As for SQLAlchemy, you can use the connect_args argument to pass a DSN
to create_engine thusly:
e = create_engine('postgresql://', connect_args={'dsn': 'user=foo
sslrootcert=root.crt'})
Cheers,
