What Is Incremental View Maintenance (IVM)?
FTA, because I don't like Jeopardy questions in headlines:
“Incremental View Maintenance (IVM) provides a method for keeping materialized views current by calculating and applying only the incremental changes, as opposed to the complete recomputation of contents performed by the REFRESH MATERIALIZED VIEW command.”
Article shows using the pg_ivm Postgres extension available here: https://github.com/sraoss/pg_ivm

a temporary-ish table vs materialize view?
There is an extension that provides some limited incremental MVIEW refresh: https://github.com/sraoss/pg_ivm

Should I replace all db select query REST APIs with a single generic router ?
It makes sense to perform managed denormalization - use a materialized view or automatically refresh a table or foreign server (via FDW) using common triggers (like pg_ivm does). And it's fine to add a TTL to it and use as a read store... update on user login and make a partial index just for that. And that's how you could get CQRS...

Features I'd Like in PostgreSQL
Good luck with that! Oracle have never made anything that they can't extract money from. In this case look to their attempts to kill logminer (which most CDC systems eg. Debezium use) and force you to pay for Goldengate hub/microservices/cloud.
Not tried it, but https://github.com/bersler/OpenLogReplicator
