Postgres DB user permission
You should log in as the table owner (the user you used to create the tables) and then grant the necessary privileges to your user:

grant select on acs_activities to your_user;


If you want to do that for all tables, you can use:

grant select on all tables in schema public to you_user;


Or maybe you created them as the superuser, but your regular user should be the real owner, then you should do:

alter table acs_activities owner to your_user;
