If you're performing an UPDATE/DELETE on your table and you don't see results for those operations from logical decoding, make sure you have set [REPLICA IDENTITY](http://www.postgresql.org/docs/9.4/static/sql-altertable.html#SQL-CREATETABLE-REPLICA-IDENTITY) appropriately for your use case.
The binary format uses simple frame encoding, which uses an 8-byte length (uint64\_t) followed by that number of bytes for the Protocol Buffer payload. The easy way to test check this out is to use _pg\_recvlogical_ like so:
pg_recvlogical -h localhost -d <yourdb> -U <youruser> -w -S decoderbufs_demo -P decoderbufs -f decoderbuf.frames -s 1 -F 1 --start
For something a bit more useful, I am looking to implement a custom PostgreSQL logical replication client that publishes to something like Apache Kafka.
