I wrote the code for the OpenTelemetry metrics I/O plugins and the underlying decoder and encoder, I'd be happy to answer any questions related to it.
Would capturing and sending OpenTelemetry metrics from the PostgreSQL codebase using the Fluent Bit C library + the OT plugin require a separate process on the host at runtime?
(in other words, does the library ship those events to a collector/transmitter process, or is everything handled in-process?)
