Description

Just installed and opened up 3.0.0-Girona. Connected to a `PostgreSQL 9.6.6 on x86_64-pc-linux-gnu, compiled by gcc (GCC) 4.8.2 20140120 (Red Hat 4.8.2-16), 64-bit` remote instance, was offered to store my credentials so I accepted. I can connected to the instance and see schemas.

I opened the DB Manager to open a SQL Window, when I click on SQL Window it says I'm not connected so I refresh connection:

#1 Updated by Raphael Dumas over 6 years ago

Just updated to 3.0.1 and this is still affected.

Interestingly this doesn't prevent loading layers from previous custom queries, but does prevent me from opening the SQL Window and loading new layers through that

I have the same issue. Also the Toolbox -> Database -> Import into PostGIS function gives the same error.

The error in 3.0.3 appears to be different (I just updated to 3.2 and they are installed beside each other at the moment).
