Description:

Hi,
I hope you can solve my problem with pgadmin 4.16.
to go straight to the point, I work with a spatial database, so use the QGis
tool, to import some spatial data and be able to visualize them in pgadmin,
the question is that when you make queries in the program it stays on the
loading screen of query tools, also doesn't let me see the contents of the
columns inside the tables.
hoping they can solve my problem.
Hoping sincerely for your response.
