postgres uses the text comparison operators provided by the host
platform. for linux these are defined in the locales package
this may be part of the glibc package.

I briefly worked for a library software company. They had defined their own
ordering operator in the form of a function that mangled strings (they were
using paradox database)
As I understand it postgres allows you to define your own types with
their own ordering operators
even ignoring the issue of non-alphabetic symbols there are problems
that should be addressed for sorting titles and names. Many of these
are due to abbreviations which shouls be sorted asif expanded.
