Jack Christensen 11b82b3ca4 msgReader implemented in terms of ChunkReader 
This should substantially reduce memory allocations and memory copies.

It also means that PostgreSQL messages are always entirely buffered in memory
before processing begins. This simplifies the message processing code.

In particular, Conn.WaitForNotification is dramatically simplified by this
change.

Jack Christensen 048a75406f Fix context query cancellation 
Previous commits had a race condition due to not waiting for the PostgreSQL
server to close the cancel query connection. This made it possible for the
cancel request to impact a subsequent query on the same connection. This
commit sets a flag that a cancel request was made and blocks until the
PostgreSQL server closes the cancel connection.

Jack Christensen b8fdc38fa8 Only store Conn's *bufio.Reader in msgReader 
Confusing and redundant to have the same *bufio.Reader in msgReader
and Conn.

Jack Christensen 90f22c1717 Don't share inet constant memory between connections 2016-05-12 08:00:53 -05:00
Jack Christensen a488fe026f Every Conn in a ConnPool gets its own PgTypes 
Rather than sharing which could allow data races.

John Barker a282d9df90 Cache connection properties in the pool 
This is a quick attempt to improve connection startup time by caching
the properties that are loaded when a connection is ready in the pool,
so that further connections don't incur this cost.

I'm not entirely convinced by the interface here, perhaps these 3 items
could live in their own type and that be passed around for clearer code,
but the idea works well.

that are created when new tables are created.

Jack Christensen 0f7bf19387 Add *Conn.SetLogLevel 
Allow changing log level after connection is established. Because
log level and loggers can be set independently, it is now possible
to have a log level above none when there is a nil logger. This
means all log statements need to check for nil logger and an
appropriate log level. This check has been factored out into
*Conn.shouldLog.
