On: Creating a search engine with PostgreSQL

The HA/DR, Sharing, Replica and Backup would all be the same as before. Its all in PG so you use the existing method.

If you have two systems, then you have two (unique) answers for HA,DR,Shard,Replica,Backup - the PG set and the Vespa.

That's more complicated, from an operational perspective.

PG FTS is quite good, and there are in-pg methods that can improve it.

And, from experience, when it's item to upscale to Solr/ES/etc it's not a very heavy lift.
