Indeed. Aside from architectural differences, I'd be very afraid of
differences in collation order (resulting in incompatible indexes on
textual columns). You might be able to make it work if you only ever
use "C" locale. But really, this is not and will never be considered
supported usage, and if it fails, no one is going to say anything
except "we warned you not to do that".
