Sort odrder in PostgreSql on Cygwin

 

Does anybody know how to change sort tables using other charachter sets (like ISO8859-2 for exemple) ?

I know, Cygwin doesn't support locale other than C  

but  I'd  like to modify  function strcmp    in  C library libc.a 

- will be  this enough? or PostgreSql's using another functions to sort characters
