OK. but I think that an aproximation to the solution or a half solution could
be deny the user consulting the system database catalog or (pg_tables). In
that case, the user is not able to know the name of the tables inside the
db, and therefore he does not know which are the tables to dump. I think
also, that pg_dump could fail at this scenario.
1. What do you think about this ?
2. Is it possible (deny the access to the system catalog or tables (like
pg_tables) to a certain user ?
Thank you very much.
