Craig Ringer a7375cc503 docs: Emphasise need to call rows.Err() after rows.Next() returns false 
The Rows interface in pgx, like its ancestor in database/sql, is easy to
accidentally misuse in a way that can cause apps to misinterpret
database or connection errors as successful queries with empty or
truncated result-sets.

Update the docs to emphasise the need to call rows.Err() after
rows.Next() returns false, and direct users of the interface to the v5
API helpers that make writing correct code easier.

The docs on Conn.Query() already call this out, so only a small change
is needed to warn users and point them at the details on Query()

Per details in #1707

Jack Christensen ae65a8007b Use higher pgconn.FieldDescription with string Name 
Instead of using pgproto3.FieldDescription through pgconn and pgx. This
lets the lowest level pgproto3 still be as memory efficient as possible.

Jack Christensen e7aa76ccf9 SendBatch now uses pipeline mode to prepare and describe statements 
Previously, a batch with 10 unique parameterized statements executed
100 times would entail 11 network round trips. 1 for each prepare /
describe and 1 for executing them all. Now pipeline mode is used to
prepare / describe all statements in a single network round trip. So it
would only take 2 round trips.
