My work on insensitive/non-deterministic collations[0] might cover this. [0]: https://www.postgresql.org/message-id/flat/1ccc668f-4cbc-0bef-af67-450b47cdfee7%402ndquadrant.com For example: CREATE COLLATION yournamehere (provider = icu, locale = 'und-u-ks-level2-ka-shifted', deterministic = false); (Roughly, ks-level2 means ignore case, ka-shifted means ignore punctuation.) -- Peter Eisentraut http://www.2ndQuadrant.com/ PostgreSQL Development, 24x7 Support, Remote DBA, Training & Services
