I would very much like it if it was opensourced like pgvectorscale and timescale extension itself

Seconded, this looks interesting but I'm __heavily__ biased towards open core stuff with value add upsells that I can opt into.

Thanks. We are already using timescale postgres image for pgvectorscale with some customizations on tsvector and GIN indexes. Would be nice to have bm25 as well. Any specific reason why this was not made open source from the get go or is it the usual phased approach by Timescale (now Tigerdata)? If not, it is a worrying signal as the same could happen with pgvectorscale development as well.

Anyways really appreciate the free offerings by timescale. Really makes things easy.
