Is your feature request related to a problem? Please describe.
NIP-45 Event Count would be great to reduce relay/client bandwidth usage when counting reactions and replies (instead of, for each thread, client having to request and download many events just to count them client-side).

Describe the solution you'd like
This relay implementation uses Postgresql, which can use the same indexes already in place when counting events.
