Should work.  In recent PG versions you would need to worry about
pg_shdepend entries too, but if you had pg_shdepend you would not have
been able to get into this state in the first place (in theory anyway).

Some general suggestions about manual changes to the system catalogs:
Reasonable prudence would suggest making the change inside a BEGIN block
and looking around for problems before you COMMIT.  If you're really
paranoid, you could first stop the postmaster and take a plain tarball
backup of the PGDATA directory tree, which would certainly let you get
back to where you were if things go horribly wrong.
