Pub/Sub support #552
Description
Is your feature request related to a problem? Please describe.
Currently only kafka support is provided for fanning out the wal stream. Adding support for other libraries/tooling would enable implementing more complex pgstream setups in different environments.
Describe the solution you'd like
Pub/Sub writer/reader support similar to what's done for Kafka. Existing official pub/sub library for go: https://pkg.go.dev/cloud.google.com/go/pubsub
Describe alternatives you've considered
Kafka is the only alternative currently supported.
Additional context
This is a GCP specific integration, other infrastructure providers can be tracked in separate issues.
