Hm. And what is returned in pw_uid?
I think you are getting burnt by initdb's attempt to assign the postgres
superuser's numeric ID to be the same as the Unix userid number of the
user running initdb. Look at the uses of pg_id in the initdb script,
and experiment with running pg_id by hand to see what it produces.
A quick and dirty experiment would be to run "initdb -i 42" (or
whatever) to override the result of pg_id. If that succeeds, the
real answer may be that pg_id needs a patch to behave reasonably on MPE.
Let us know...
