Detailed Description

String conversion traits for binarystring.

Defines the conversions between a binarystring and its PostgreSQL textual format, for communication with the database.

These conversions rely on the "hex" format which was introduced in PostgreSQL 9.0. Both your libpq and the server must be recent enough to speak this format.
