There are lots of options to stream data out of Postgres, including:
- https://electric-sql.com (disclaimer: co-founder) - https://feldera.com - https://materialize.com - https://powersync.com - https://sequinstream.com - https://supabase.com/docs/guides/realtime/broadcast - https://zero.rocicorp.dev
Etc.
I think these all relate to streaming data. Not streams in the sense of the data-structure for message passing (a la Kafka, Redis Streams, etc)
The logical replication of the transaction log is basically a stream of data change events, so the difference between those senses isn’t very big.
