* 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
* Remove double-send of ssl request packet
I missed the fact that we are already sending this. Since I don't have good test coverage for ssl [which I am planning on fixing next](https://github.com/brianc/node-postgres/issues/2009) this got missed.
I'm forcing an SSL test on travis. This will break for me locally as I don't have SSL enabled on my local test DB. Something I will also remedy.
