Comment 4 for bug 1773763

This branch fixes the test: https://code.launchpad.net/~ahasenack/ubuntu/+source/skytools3/+git/skytools3/+ref/fix-dep8-new-postgresql

I also tried with the original xenial postgresql version, tests also pass there, i.e., this modification doesn't break them.

The diff in the test output is this:

It's adding the "public." prefix to the "events_2011-01" table name, and compensating for the extra length in the output (whitespace and --- chars).
