8cd94a14c7 Allow types to specify preference format result and param formats 
This will be useful for array and composite types that may have to
support elements that may not support binary encoding.

It also is slightly more convenient for text-ish types to have a default
format of text.

52729c1b77 Back off some aggressive PlanScan optimizations 
PlanScan used to require the exact same value be used every time. While
this was great for performance, on further consideration I think it is
too much of a potential foot-gun.

This moves back in the other direction. A plan tolerates a change in
destination. It even detects a change in destination type and falls
back to a new plan.

Perfectly matched hot scan paths (e.g. PG int4 to Go int32) are still
much faster than they were before this set of optimizations. The first
scan of a destination that uses a decoder is faster due to not
allocating. It's a little bit slower on subsequent runs than before
this set of optimizations. But it is preferable to optimize for the
most common scan targets (e.g. *int32, *int64, *string) over generic
decoder destinations.

In addition this fees pgx.connRows.Scan from having to check that
the destination is unchanged.

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.

97bbe6ae20 Add RegisterDefaultPgType 
This allows registering a mapping of a Go type to a PostgreSQL type
name. If the OID of a value to be encoded or decoded is unknown, this
additional mapping will be used to determine a suitable data type.

c44cda4bb4 Clean up old Go 1.10 build tags 
pgx requires Go modules which requires at least Go 1.11 so there is no
use in build tags to support older Go versions.

c03ac1519e Improve stdlib performance with large result sets 
In a hot path type assertions are expensive. Cache the already correctly
typed interfaces. ~20% improvement with 1000 rows.

4a50a63f12 Refactor Scan optimization 
Instead of hardcoding specific types and skipping type assertions based
on that, only check if a destination is a (sql.Scanner) after a failed
AssignTo.

This is slightly slower in the non-decoder case and *very* slightly
faster in the decoder. However, this approach is cleaner and has the
potential for further optimizations.
