chore(refactor): multiple changes/cleanups Simplify 'for x in [list val]; alist.append(x)' to 'alist = list([list val])'. Easier to read as copy of list. Also twice as fast although speed not an issue. Remove unneeded list() wrappers. Replace set(list comprehension) with set comprehension. Also add trailing ,'s to last element in tuples/lists. Add some noqa items for acceptable operations in context. Switch " ... \" ...\" ..." to: ' ... " ... " ...' to remove need to escape internal '"'. Change 'not x in y' to 'x not in y'.

# simple way to see if there are order dependencies in tests
# can use if pytest-random-order --random-order mode isn't
# usable (e.g. python2).

# Add a marker for pg_schema tests.
# They duplicate the postgresql tests exactly but uses a named
# schema rather than the default 'public' schema.
