* Fix error handling test
#2569 introduced a bug in the test. The test never passed but because travis-ci lovingly broke the integration we had a long time ago the tests weren't run in CI until I merged. So, this fixes the tests & does a better job cleaning up the query in an errored state.
* Update sponsors
Based on the suggestion from #2078. This adds ref/unref methods to the
Connection and Client classes and then uses them to allow the process to
exit if all of the connections in the pool are idle. This behavior is
controlled by the allowExitOnIdle flag to the Pool constructor; it defaults
to the old behavior.
It’s missing `co.wrap`, so it doesn’t actually run (Mocha does nothing with the paused generator). The test group that follows it, “using an ended pool”, covers the same thing anyway.
* Prevent requeuing a broken client
If a client is not queryable, the pool should prevent requeuing instead
of strictly enforcing errors to be propagated back to it.
* Write tests for change
* Use node 13.6 in travis
Some weird behavior changed w/ async iteration in node 13.7...I'm not sure if this was an unintentional break or not but it definitely diverges in behavior from node 12 and earlier versions in node 13...so for now going to run tests on 13.6 to unblock the tests from running while I track this down.
* Update packages/pg-pool/test/releasing-clients.js
