How about each user can set up a list of authorised users that
are allowed to switch to their username.

This would then follow the same model as authorized_keys/.rhosts in
ssh/rsh

user1 could then call something like
> GRANT SESSION TO user2
which would allow user2 to switch to user1


Would it also be possible to restrict the grants when doing this?

e.g.
> GRANT SESSION SELECT ON DATABASE foo TO user2
> GRANT SESSION UPDATE ON TABLE bar TO user2

Which would allow updates to be made to table bar after the switch.
