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.

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.

fef3ffc391 Link to pkg.go.dev instead of godoc.org 
This is a big improvement because it can directly link to the v4 docs
instead of the pre-modules v3. The badge should be changed once the new
pkg.go.dev badge is available.

WGH
c01721e3ba Add Len() method to *pgx.Batch 
This makes the API slightly easier to use when number of calls to
Queue() cannot be trivially computed.

For example, if the program contains the loop like the following,
a separate variable counting the iterations is needed:

    numHeaders := 0
    for _, header := range prepareHeadersForInsert(*res.Headers) {
        headerBatch.Queue("INSERT ...", ...)
        numHeaders++
    }

    headerBatchResult := tx.SendBatch(ctx, headerBatch)

    for i := 0; i < numHeaders; i++ {
        _, err := headerBatchResult.Exec()
        // ...
    }

With method Len(), this extra variable can be eliminated.
