As you see ONLY the 00000000000000CS ID is missplaced,
the others are in correct sequence! This isn't a locale specific

Still looks like locale to me. Exactly what LANG or LC_xxx settings
are you using for the postmaster?

As a note, using a test program with LC_COLLATE=hu_HU, I get the
following strcoll values. ( I'm sort of assuming that hu_HU would
be the default setting for Hungary ;) )

CS <=> CY = 1
CS <=> CZ = -1

That seems to imply that for hu_HU CSs collation value is between
CY and CZ.

On HPUX 10.20, I get these results:

(HPUX is picky about locale names... 'hu_HU' doesn't work...)

This doesn't seem to entirely square with the results you two get,
but it sure does look like "CS" sorts in non-ASCII order in HU locale.

I tried it with the full locale name you used and sort with that data and
still got the same result as I did before (CY/CS/CZ) which seems odd that
it's different, but it's on a Debian box which I'd guess should be pretty
similar to the Red Hat machine of the original complaintant (sp?).
