No, what it sounds like is the OP tried to physically replicate a
database on another platform with completely different sorting rules.
Which means all his text indexes are corrupt according to the
destination platform's sorting rules, which easily explains the
observed misbehavior (ie, index searches not finding the expected rows).
REINDEX would fix it. But the major point here is you can't just ignore
a collation mismatch, which in turn implies that you can't do physical
replication from Linux to Windows, or vice versa (and most other
cross-platform cases are just as dangerous).

Then you might as well just rm -rf it (or whatever the equivalent Windows
incantation is). On Windows, that database is broken and useless.
