Jack Christensen f3816bd1c0 Get implemented on T instead of *T
Methods defined on T are also available on *T. Thought this technically
changes the interface, because *T will be automatically dereferenced as
needed it shouldn't be a breaking change.

See a8802b16cc for similar change.

Jeffrey Stiles 06942241c4 Support Null Status in UnmarshalJSON 2020-01-24 16:38:15 -08:00
Jack Christensen a8802b16cc Value, EncodeBinary, EncodeText, and MarshalJSON on T instead of *T
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.

Jack Christensen ab21bc4ec7 pgtype DecodeText and DecodeBinary do not copy
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.

Jack Christensen 6e21cb00fe Add pgtype.Record and prerequisite restructuring
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.

Jack Christensen a79b498533 Remove Set self support from pgtype
Set having the capability to assign an object of the same type was
inconsistently implemented. Some places it was not implemented at all, some
places it was a shallow copy, some places a deep copy. Given that it doesn't
seem likely to ever be used, and if it is needed it is easy enough to do
outside of the library this code has been removed.

Jack Christensen e654d1f0fc pgtype.Encode(Binary|Text) do not write length
To aid in composability, these methods no longer write their own length. This
is especially useful for text formatted arrays and may be useful for future
database/sql compatibility. It also makes the code a little simpler as the
types no longer have to compute their own size.

Along with this, these methods cannot encode NULL. They now return a boolean
if they are NULL. This also benefits text array encoding as numeric arrays
require NULL to be exactly `NULL` while string arrays require NULL to be
`"NULL"`.
