> Depending on which compression codec is used, a short read of the compressed
> bytes can cause catastrophic errors that confuse the WAL reader. This problem
> can manifest when the reader is actively tailing the WAL for replication. The
> input stream's available() method sometimes lies so cannot be relied upon. To
> avoid these issues, when WAL value compression is enabled, ensure all bytes
> of the compressed value are read before submitting the payload to the
> decompressor.
