Really depends on your needs. There are lots of options out there that are happy to talk to Postgres, but each has different strengths and weaknesses. If all you need is a way to basically share and visualize the output of SQL queries and everyone who's using the tool can write SQL well, then look at Periscope or Mode.

If you're ok pulling the data out of Postgres into memory locally and mostly care about manipulation and beautiful dataviz, then look at Tableau.

If you're mostly interested in more data sciency/ML stuff, then Shiny or something else that's R-based is a good option.

If you're interested in being able to embed your business logic into the tool so that non-SQL folks can build their own queries and everybody's relying on the same data definitions, that's where Looker (disclosure: where I work) excels.
