* Use container-based CI
* Remove unnecessary CI configuration
* Use Node 6/PostgreSQL 9.6 as default test
… rather than testing 0.10 twice with unspecified PostgreSQL.
* Use `precise` for PostgreSQL 9.1
According to https://docs.travis-ci.com/user/database-setup/, 9.1 isn’t supported on trusty.
* Fix Node 0.10 and 0.12 CI builds
These binaries appear to have been built using g++ with flags that clang doesn’t support. Or something.
Setting PostgreSQL 9.5 as the main version to test against.
NOTE: The following settings are required for 9.5 to work:
```
sudo: required
dist: trusty
```
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.
