It took me a long time to understand how this works (e.g. that PGPORT is
still required to be set for psql to find the correct domain socket.)
But I think I'm now a bit clearer.

I tried setting this to "" globally and it seemed to work; is there any
reason to treat postgres 10 and 11 specially?

More fundamentally, is there any reason we particuarly want to do things
this way on Travis?
