Eh? How you store collations names is easy. Every collation has a
textual name which is what we store in the catalog. I'm not sure why
you'd think it'd be any more complicated than that. And it has
precisely nothing to do with ICU and everything to do with being able
to support multiple source of collation information. We already have
two: builtin (strcmp/memcmp) and C library (strcoll). Letting peope add
more is the goal.
I'm sure once the catalog exists the existing ICU-for-Postgres patch
will be adjusted to use it.
Have a nice day,
