[Qgis-user] QGIS3: layer is not valid (PostGIS)

[Tobias Wendorff]

Hi there,

whenever I'm working with PostgreSQL (PostGIS) layers in QGIS3, I'm
getting this error after a few minutes:

Layer is not valid : The layer dbname='geodata' host=<hidden> port=5432
user='<hidden>' password='<hidden>' sslmode=allow srid=25832 type=Point
table="leg"."demo1" (geom) sql= is not a valid layer and can not be added
to the map. Reason:

There's no reason, the layer is still valid. After a full restart,
I can access the layer without a problem.

Anyone with an idea, what's wrong here?

Best regards,
Tobias
