A long standing bug was the pure JS client didn't accept or call a callback on `client.end`. This is inconsistent with both the documentation & general node patterns.
This fixes the issue & adds a test. The issue did not exist in the native version of the client.
The promise adapter I had implemented wasn't spec compliant: it didn't accept both `onSuccess` and `onFailure` in the call to `query#then`. This subtly broke yield & async/await because they both rely on `onError` being passed into `Promise#then`. The pool was also not returning the promise after a client was acquired, which broke awaiting on `pool.connect` - this is also fixed now.
* Initial work on removing internal pool
* Port backwards-compabible properties
* Cleanup test execution & makefile cruft
* Attempt to fix flakey error test
* Make Query & NativeQuery implement the promise interface
* Fix test
* Use older node API for checking listener length
* Do not test for promises on node@v0.10.0
When user provides a knex select statement with an undefined options in where clause it is not properly handled an give an ambiguous error message telling `Unhandled rejection TypeError: Cannot read property 'toString' of undefined.` This PR will helpful to users at it will tell them the exact problem.
There was some nasty global-ish variable reference updating happening when the native module 'initializes' after its require with `require('pg').native`
This fixes the issue by making sure both `require('pg')` and `require('pg').native` each initialize their own context in isolation and no weird global-ish references are used & subsequently stomped on.
I noticed that query cancellation was not working when connecting through pgbouncer,
even though it worked fine when directly connected. This is because we're appending an
extra null byte, and pgbouncer is strict about the packet length.
(per http://www.postgresql.org/docs/9.1/static/protocol-message-formats.html)
This removes the extraneous byte, which fixes cancellation against pgbouncer.
When a __prepared statement__ has no body in the query the backend responds with an `emptyQuery` message but never with a `commandComplete` or `errorResponse` message. The client was hanging forever waiting for one of the other two expected messages. The server was hanging forever waiting for the client to respond with a `sync` message. This change has the client send the required `sync` on receipt of an `emptyQuery` message when the query is a prepared statement. Fixes#822
Postgres has a 63 character limit on query names. To avoid potential footgunning of users we'll log to their stderr if they use a longer query name.

The code is failing with pg-copy-streams. The pg-copy-streams creates a query object but it doesn't have any _result. Make the type parser an optional only when _result object available on query then only set the type parser.
Fixes a case where you connect & immediatley disconnect and _sometimes_ your notification subscription starts the reader on the libpq instance after the libpq instance is disconnected. This segfaults the app.
