The two collations will probably not behave identically, since PostgreSQL uses the
operating system collations instead of having ist own, and odds are that Microsoft's
collations and glibc's are slightly different.

I don't know if the impact will be large; maybe run a couple of tests to see if the
ordering is similar enough for your purposes.

I don't think that the actual encoing (UTF-8 or Windows-1252) has any impact on the ordering,
but I am not certain.
