Description

The PostGIS example in the docs for PersistDbSpecific stores the data extracted from the db as a hex encoded (Byte)String, as opposed to the underlying binary data which includes the full range of bytes instead of just 0-F.

This seems inefficient both speed-wise and memory-wise, so I was wondering if it was possible to efficiently get at that underlying binary data.

Research direction

Start with the PersistDbSpecific documentation and its PostGIS example. Investigate how the example extracts database data and whether the underlying binary value is exposed rather than a hex-encoded ByteString. Done means documenting or providing an agreed efficient way to access the raw binary data.
