Jack Christensen 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.

pgtype

pgtype implements Go types for over 70 PostgreSQL types. pgtype is the type system underlying the https://github.com/jackc/pgx PostgreSQL driver. These types support the binary format for enhanced performance with pgx. They also support the database/sql Scan and Value interfaces and can be used with https://github.com/lib/pq.
