Well, from my BSD manual it says:
    The setuid() function sets the real and effective user IDs and the saved    set-user-ID of the current process to
thespecified value.  The setuid()
 

so it seems to make sure the real/saved uid matches the effective uid. 
Now, considering we don't use uid/euid distinction for anything, I agree
it is useless and should be removed.

I don't see any mention of getuid() except in odbc and pg_id.  Seems
they should be geteuid() too.
