I have a multi-tenant PostgreSQL db on a Ruby on Rails app, and when I try to access to tables on some schemas on Postico, I get the following error:
Failed to load table schema.
Query failed
PostgreSQL said: permission denied for schema coaching
I tried to run: GRANT USAGE ON SCHEMA "lacerba-api" TO "postico7"
but I get ERROR: permission denied for schema lacerba-api
Of course my user have writing permission on the db.
Any idea how to solve it?
