Methods defined on T are also available on *T. This change makes Value
consistent with database/sql Value implementations. It also makes Value,
EncodeBinary, and EncodeText more convenient to use because you can
pass T or *T as an argument to a query.
The MarshalJSON change is even more significant because without it
json.Marshal would generate the "%v" format instead of the implemented
MarshalJSON.
Thought this technically changes the interface, because *T will be
automatically dereferenced as needed it shouldn't be a breaking change.
See: https://github.com/jackc/pgx/issues/538 for initial discussion.
They now take ownership of the src argument.
Needed to change Scan to make a copy of []byte arguments as lib/pq apparently
gives Scan a shared memory buffer.
This adds PostgreSQL numeric mapping to and from
github.com/shopspring/decimal.
Makes pgtype.NullAssignTo public as external types need this functionality.
Begin extraction of pgtype testing functionality so it can easily be used by
external types.
Because reading a record type requires the decoder to be able to look up oid
to type mapping and types such as hstore have types that are not fixed between
different PostgreSQL servers it was necessary to restructure the pgtype system
so all encoders and decodes take a *ConnInfo that includes oid/name/type
information.
Though this doesn't follow Go naming conventions exactly it makes names more
consistent with PostgreSQL and it is easier to read. For example, TIDOID becomes
TidOid. In addition this is one less breaking change in the move to V3.
