Glab to see more 'postgres-native' full-text search implementation.

Alternative solutions (lucene/ tantivy) are both designed for 'immutable segments' (indexing immutable files), so marrying them with postgres heap table would results in a worse solution.

[retakeming]

The segments themselves being immutable doesn't mean that Tantivy is incompatible with Postgres - it just means that Tantivy needs to be made compatible with Postgres' concurrency control mechanisms (MVCC) and storage format (block storage). This blog post explains the latter: https://www.paradedb.com/blog/block_storage_part_one

the fundamental mismatch i saw is "creating a new segment for each individual dml", it is possible to alleviate but i don't think there's a good general solution.
