* Add tests for query callbacks after connection-level errors
* Ensure callbacks are executed for all queued queries after connection-level errors
Separates socket errors from error messages, sends socket errors to all queries in the queue, marks clients as unusable after socket errors.
This is not very pleasant but should maintain backwards compatibility…?
* Always call `handleError` asynchronously
This doesn’t match the original behaviour of the type errors, but it’s correct.
* Fix return value of `Client.prototype.query` in immediate error cases
* Mark clients with closed connections as unusable consistently
* Add tests for error event when connecting Client
* Ensure the promise and callback versions of Client#connect always have the same behaviour
* Give same error to queued queries as to active query when ending
and do so in the native Client as well.
* Restore original ordering between queued query callbacks and 'end' event
PostgreSQL 10 reports its version as only `major.minor`, so it can’t be parsed with semver. The `server_version_num` setting is a major version followed by a four-digit minor version since version 10, and was a three-digit major version followed by a two-digit minor version before that.
* Work on converting lib to standard
* Finish updating lib
* Finish linting lib
* Format test files
* Add .eslintrc with standard format
* Supply full path to eslint bin
* Move lint command to package.json
* Add eslint as dev dependency
* Add client connectionString tests (#1310)
* Remove redundant tests
* Add client connectionString test
Add test to ensure { connectionString } is respected as an argument to the client constructor
* Add test for connection string property
Also fixed some legacy require statements.
* Normalize native error properties
Map native error properties to the same property names we use for errors from the JS driver.
