Hi. on a freshly installed 10.6 I can see all ICU collations added in
pg_collation schema. Is there a way to have them for an existing
database cluster?

There's a function called something like pg_import_system_collations.
See documentation.

Thanks a lot!

postgres=# select pg_import_system_collations('pg_catalog');
 pg_import_system_collations
-----------------------------

postgres=# select pg_import_system_collations('pg_catalog');
