Review comment:
This is pretty subtle now, in that the trailing slash is important.
`https://some.host/proxied/avatica` is unique to
`https://some.host/proxied/avatica/` in that the first is parsed as:
`{'endpoint':'https://some.host/proxied', 'schema':'avatica'}` and the second
is parsed as `{'endpoint':'https://some.host/proxied/avatica', 'schema':''}`.
(edit, typo'ed)
Looking at other DSN's, this is a pretty common convention. However, most
databases don't allow/expose querying from behind a normal http loadbalancer ;)
Is it going to be less error prone if we let the default schema to be
provided via a query string instead of the path?
