tl;dr: TIN is a new Postgres full-text search extension that uses Postgres ctids directly as document identifiers (rather than sequential IDs like ParadeDB or pg_textsearch), enabling two-level bitmap encoding that fits into AVX2/AVX-512 registers for vectorized intersection/union operations. Benchmarks show TIN delivering 8–500× higher throughput than ParadeDB, pg_textsearch, and Postgres GIN across conjunction, disjunction, phrase, and count queries, while also avoiding segment renumbering during merges and integrating cleanly with MVCC via visibility-map intersections.
