Support connstring DSNs (host=... user=... password=... dbname=...) in
addition to URIs (postgresql://user:pass@host/dbname) for purposes of
database discovery.

Connstring syntax is needed to support accessing PostgreSQL via Unix
domain sockets (host=/run/postgres), which is not really possible with
URI syntax.

Fixes: #293
