* pgsql: pg_unicode_fast: fix final sigma logic. @ 2026-07-07 21:54 Jeff Davis <jdavis@postgresql.org> 0 siblings, 0 replies; 3+ messages in thread From: Jeff Davis @ 2026-07-07 21:54 UTC (permalink / raw) To: pgsql-committers@lists.postgresql.org pg_unicode_fast: fix final sigma logic. If the string is preceded only by Case Ignorable characters, don't consider it to be a final sigma. In the process, refactor so that the preceding and following characters are found first, and then the rule is applied, to improve clarity.
