I'd like a lightweight alternative to pgAdmin4 ?

Hi
call me oldfashioned but I'd like to have a lightweight alternative to 
pgAdmin4.

pgAdmin3 does in 99% of the time all I have to do with PG, throwing SQL 
at the server and getting some stuff back.
It starts fast, offers multi-window and drag&drop of scripts into the 
editor.

I really do appreciate all the work put into PG and pgAdmin4
but pgAdmin4 is more nice to look at than to work with.

pgAdmin3 sadly doesn't like PG 10, so I'm looking in a dead end.

Is there any other tool to talk with PG that doesn't carry so much bulk?


Regards
Andreas
