Crate mz_pgrepr

Representation of and serialization for PostgreSQL datums.

This crate exports a Value type that maps directly to a PostgreSQL datum. These values can be serialized using either the text or binary encoding format; see the mz_pgwire_common::Format type for details.

Values are easily converted to and from mz_repr::Datums. See, for example, the values_from_row function.
