Ben SchumacherandGitHub 54438407cf [MM-67671] Add CJK Post search support for PostgreSQL (#35260)
Add LIKE-based CJK (Chinese, Japanese, Korean) search support for PostgreSQL, gated behind a `CJKSearch` feature flag.

PostgreSQL's built-in full-text search (`to_tsvector`/`to_tsquery`) does not support CJK languages because it relies on whitespace-based tokenization, which doesn't work for logographic/syllabic scripts that don't use spaces between words. This PR adds a `LIKE`-based fallback for search terms containing CJK characters.

**How it works:** When the `CJKSearch` feature flag is enabled and a search term contains CJK characters (Han, Hiragana, Katakana, or Hangul), the query builder generates `LIKE '%term%'` clauses instead of `to_tsvector @@ to_tsquery` expressions. Case-sensitive `LIKE` is used rather than `ILIKE` since CJK scripts have no letter casing, which also allows potential use of standard B-tree indexes.
