Jack Christensen 38dd42de4b Support new pgtype format preferences 2020-05-10 14:09:02 -05:00
Jack Christensen a66b09fbd8 Improve simple protocol / text format 
Increased data type support for simple protocol. Improved test
coverage of simple protocol. This has the additional advantage of
exercising the text encoders and decoders.
 2020-05-08 16:20:15 -05:00
Jack Christensen be9ceaefe6 Add native Go slice support for strings and numbers to simple protocol 
[]string, []int16, []int32, []int64, []int, []uint16, []uint32,
[]uint64, []uint, []float32, and []float64 are now supported in the
simple protocol like they are in the normal usage of the extended
protocol.

Jack Christensen 6972a57421 pgtype.OID type should only be used for scanning and encoding values 
It was a mistake to use it in other contexts. This made interop
difficult between pacakges that depended on pgtype such as pgx and
packages that did not like pgconn and pgproto3. In particular this was
awkward for prepared statements.

This is preparation for removing pgx.PreparedStatement in favor of
pgconn.PreparedStatement.

Wow. This is fun. Sure is easy to get modules wrong when upgrading a v2+
project.

Jack Christensen 9c8ef1acdd Fix pgtype types that can Set database/sql/driver.driver.Valuer 
Bug was chooseParameterFormatCode would see that type could handle
binary format so binary format would be chosen. But
encodePreparedStatementArgument would see driver.Valuer first and
would encode with that -- which is text mode. So the server would
receive a text format value when expecting a binary format value.

Jack Christensen 19c6689752 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 743b98b298 Name PG types as words 
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.

Jack Christensen 1f3e484ca1 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"`.
