* Remove password from stringified outputs (#2066)

* Remove password from stringified outputs

Theres a security concern where if you're not careful and you include your client or pool instance in console.log or stack traces it might include the database password.  To widen the pit of success I'm making that field non-enumerable.  You can still get at it...it just wont show up "by accident" when you're logging things now.

The backwards compatiblity impact of this is very small, but it is still technically somewhat an API change so...8.0.

* Implement feedback

* Fix more whitespace the autoformatter changed

* Simplify code a bit

* Remove password from stringified outputs (#2070)

* Keep ConnectionParameters’s password property writable

`Client` writes to it when `password` is a function.

* Avoid creating password property on pool options

when it didn’t exist previously.

* Allow password option to be non-enumerable

to avoid breaking uses like `new Pool(existingPool.options)`.

* Make password property definitions consistent

in formatting and configurability.

* Make `native` non-enumerable (#2065)

* Make `native` non-enumerable

Making it non-enumerable means less spurious "Cannot find module"
errors in your logs when iterating over `pg` objects.

`Object.defineProperty` has been available since Node 0.12.

See #1894 (comment)

* Add test for `native` enumeration

* Use class-extends to wrap Pool (#1541)

* Use class-extends to wrap Pool

* Minimize diff

* Test `BoundPool` inheritance

* Continue support for creating a pg.Pool from another instance’s options (#2076)

* Add failing test for creating a `BoundPool` from another instance’s settings

* Continue support for creating a pg.Pool from another instance’s options

by dropping the requirement for the `password` property to be enumerable.

* Use user name as default database when user is non-default (#1679)

Not entirely backwards-compatible.

* Make native client password property consistent with others

i.e. configurable.

* Make notice messages not an instance of Error (#2090)

* Make notice messages not an instance of Error

Slight API cleanup to make a notice instance the same shape as it was, but not be an instance of error.  This is a backwards incompatible change though I expect the impact to be minimal.

Closes #1982

* skip notice test in travis

* Pin node@13.6 for regression in async iterators

* Check and see if node 13.8 is still borked on async iterator

* Yeah, node still has changed edge case behavior on stream

* Emit notice messages on travis

* Revert "Revert "Support additional tls.connect() options (#1996)" (#2010)" (#2113)

This reverts commit 510a273.

* Fix ssl tests (#2116)

* Convert Query to an ES6 class (#2126)

The last missing `new` deprecation warning for pg 8.
