Hi,
The 'locale' or 'lc_collate/lc_ctype' argument of an ICU collation may
have a complicated syntax, especially with non-deterministic
collations, and input mistakes in these names will not necessarily be
detected as such by ICU.
The "display name" of a locale is a simple way to get human-readable
feedback about the characteristics of that locale.
pg_import_system_collations() already push these as comments when
creating locales en masse.
I think it would be nice to have CREATE COLLATION report this
information as feedback in the form of a NOTICE message.
PFA a simple patch implementing that.
Best regards,
