I searched for the Postgres extension and enabled it. Azure Data Studio tells me it is installed:

Name: PostgreSQL
Id: microsoft.azuredatastudio-postgresql
Description: PostgreSQL extension for Azure Data Studio
Version: 0.2.2
Publisher: Microsoft
VS Marketplace Link: undefined?itemName=Microsoft.azuredatastudio-postgresql

But when it installed (and everytime I restart Azure Data Studio), I get this error:

[Error - 3:51:27 p.m.] Connection to server got closed. Server will not be restarted.

Although the connection type Postgres now shows, it just loops forever trying to connect. I can connect just fine usign psql or HeidiSQL.
