A few moments with grep would've showed you that the WARNING means no
rows were found in a seqscan of pg_authid. The system is able to plow
ahead anyway in single-user mode, but then it evidently also can't find
the row that should exist in pg_database for template1. So yeah,
something is wrong with your storage stuff; the rows inserted during
bootstrap aren't getting found, or aren't visible, or some such, during
a subsequent single-user-mode run.
I'd suggest running initdb with --noclean and then trying to start a
standalone backend by hand under gdb, so you can trace through things
and see why it's not seeing the rows. You could also eyeball the
so-far-created files to see if they contain what you expect.
