CrateDB might be a good fit for full text and vector search (it’s SQL database but has dedicated clauses for FT and VS). Curious how do you use PG for key/value and queue - do you use regular tables or some specific extensions? I can imagine kv being a table with primary key on “key” and for queue a table with generated timestamp, indexed by this column and peek/add utilising that index.
