If I have restricted those permissions (i.e. access to specific schemas
only, allowing specific operations - like INSERT only on just the tables
needed for that particular db user) how would a user, who hijacked the
connection, be able to "at least copy, and probably modify user data" then?

They give a comprehensive information about the entire structure of the
database - that, at least to me, is good-enough reason to restrict such
an access.
