You might encounter the below error while accessing a database object in Postgres database.
Error : permission denied for relation <your_object_name>
The issue here is that you do not have privileges granted on the database object <your_object_name> to your user account.
You should grant the required privileges on the database object to the user to resolve the error.
If your database object is a table, and the user is trying to select from the table, run the below grant statement(as a super user or schema owner):
grant select on <your_table_name> to <username>;
You can also grant insert, update, delete or ALL privileges on the table to the user/group as required. It is a best practice to always grant minimum required privileges on the database objects to users.
If your database object is a function, run the below grant statement:
grant execute on function func_name(a integer, b varchar) to <username>;
