That would be hard. There is an option to make psql show the queries
it uses to implement \d. Reading that  it is normally easy to buld a
query which lists the dependents by creative imitation and feed it to
psql ( instead of the \d ) with the approppiate context setting
options to spit the table names, or even the --table="xx" list,
including schemas and other niceties.

And if his shell is not bash, but CMD.EXE or other similar thing,
parsing \d output will be hell.
