A while ago, I posted a pull request for PostgreSQL auto-reconnect,
got some feedback on that, went back and tried again. I have had a
second pull request up for quite a while now including tests that
reveal the failure to reconnect (still broken or re-broken after
#6477) and a fix for that problem.
This fixes a currently open issue for my employer if I can get it
accepted and subsequently get that applied to the Rails versions our
applications are using.
I'm still waiting to have my pull request accepted or rejected.
