I'm not sure what "change the arguments sent to SQL" means. A
malicious user with sufficient privileges can do all sorts of damage,
and there's not much much you can do about it short of not letting
malicious users have privileges.

your foreign data wrapper code should probably require that the user who
creates a FDW connection to an external database have adequate
permissions. the foreign database servr already has its own
authentication hoops tha this FDW user will have to provide.
