Jack Christensen dea915e605 Compare binary and text format through pgx 
Make ID field bigger -- otherwise all ints are less than 4 digits and
get a bit too much of an advantage in text vs. binary

Jack Christensen c3e41872a8 Resplit Begin and BeginEx 
This is in preparation for a Begin / Tx interface that will similate
nested transactions with savepoints.

In addition, this passes the TxOptions struct by value and thereby
removes an allocation.

Jack Christensen 3028821487 Add context.Context to Logger interface 
This allows custom logger adapters to add additional fields to log
messages. For example, a HTTP server may with to log the request ID.

Jack Christensen f572b336b1 Improve pool Acquire / Release performance 
Release was using a goroutine every time. Now it only starts a goroutine
when doing something that may take a while. (Destroy and afterRelease)

Jack Christensen efb333df6b Fix go modules 
Wow. This is fun. Sure is easy to get modules wrong when upgrading a v2+
project.

Jack Christensen 66625e6489 Prepare takes context 
Also remove PrepareEx. It's primary usage was for context. Supplying
parameter OIDs is unnecessary when you can type cast in the query SQL.
If it does become necessary or desirable to add options back it can be
added in a backwards compatible way by adding a varargs as last
argument.

Remove SelectValue
 2014-07-05 18:23:19 -05:00
Jack Christensen 5b345e80e1 Remove SelectValueTo 
Benchmarks revealed that it is no longer performant enough to pull
its own wait. Using go_db_bench to copy JSON results to HTTP responses
it was ~20% *slower* for ~4BK responses and less than 10% faster for
+1MB responses.

The the performance problem was in io.CopyN / io.Copy. io.Copy
allocates a 32KB buffer if it doesn't have io.WriterTo or io.ReaderFrom
available. This extra alloc on every request was more expensive than
just reading the result into a string and writing it out to the response
body.

Tests indicated that if MsgReader implemented a custom Copy that used a
shared buffer it might have a few percent performance advantage. But the
additional complexity is not worth the performance gain.
