Re: Case Insensitive Comparison with Postgres 12

Hello,
use correct locale identifier, in your case it should be:
create collation "case_insensitive" (provider=icu,
locale="en-US-u-ks-level2", deterministic = false);

See
http://www.unicode.org/reports/tr35/tr35-collation.html#Setting_Options
for available options.
