[postgis-users] No extension

This I suppose could be a permission issue or search path one.


Are you using the same account in QGIS to connect as you are in pgAdmin?


Are you connecting from QGIS PostGIS layers or via QGIS DBManager menu option?


If you haven’t tried DBManager, I would try that to see what tables you are able to see.  That should give you a clue if it’s a permission issue.

Thanks for the reply.

It returns a data grid showing all the spatial layers.

The strange thing was that it had been uninstalled. I removed the rogue connection in PgAdmin 4 and it fixed the problem.

In my new instance I created a database for each of the backup databases, execute "create extension postgis" for all of them, then restored the original data from the backups successfully. I am still getting this in qGIS logs...

2022-09-29T14:38:36     WARNING    No PostGIS support in the database.

2022-09-29T14:38:36     WARNING    Database connection was successful, but the accessible tables could not be determined.
