sql-studio shouldn't require a password for clickhouse and postgres

[zoechi]

I tried to connect to freshly installed clickhouse and postgres for a development environment but sql-studio shouts at me that the password is missing.
With clickhouse-client and psql I can connect without a password just fine.

I also was not able to connect using unix sockets with sql-studio. I haven't looked into the code, but with Postgres I think sql-studio shouldn't try to parse the connection string, but just pass it forward.

With Clickhouse I don't have any experience how connection works.
