I'm pretty suspicious of incompatibilities that may exist between the
two sets of OS collations involved here. We aren't very clear on the
extent to which what you're doing is supported, but it's certainly the
case that bttextcmp()/varstr_cmp()/strcoll() return values must be
immutable between the two systems. Still, it should be possible to
determine if that's the problem using btreecheck.

Do you get perfectly consistent answers between the two when you ORDER BY login?
