I nearly bought this when it launched due to how frustrated I get with pgAdmin.

As other posters noted its missing a lot of features. I knew my frustrations would not be solved.

I use IntelliJ's database stuff instead, which I "discovered" as a result for my hunt for the PGSQL admin tool after Postico's announcement. (Until that point I had largely avoided IDE database stuff because they often try to make you do insane things, like use the mouse to design tables.) When I considered the price of purchase for a stand alone PGSQL admin tool and an IntelliJ personal license [including yearly renewals] it became pretty clear what the correct choice for me was.

In terms of the things I need to do as a software engineer in regards to PGSQL, IntelliJ has everything I need; plus in recent versions IdeaVIM works more reliably.
