- Generated service names come only from a URL host, a key=value DSN's
host=, or a MySQL tcp() address, so a password in a key=value DSN can no
longer end up in the name printed on every log line.
- connect_timeout is added only to postgres:// and postgresql:// URLs
(parsed, so it never lands after a fragment) or as a key=value token, never
glued onto a key=value value containing "://".
- Driver parse errors that quote password fragments (mongo escape errors,
lib/pq's missing "=" error) are replaced with generic hints.
- MongoDB keeps its client only after a successful connect, so a failed
connect is not disconnected twice.
- Couchbase gets ready_timeout plus 1 minute to connect, so raising
ready_timeout takes effect.
- Shutdown waits at most 7 seconds, inside Docker's 10-second grace period.
- Each adapter declares its config keys; unknown keys anywhere in the file,
including under config, log a warning without blocking start.
