This is great! One thing I modified was adding -- (start=+\v(--|ALTER|BEGIN|...) to catch strings that start with a comment.
The other thing I can't seem to figure out how to solve is it doesn't work for me with arrays containing triple quotes. For example:
# works fine
x = """
-- this works fine
select * from x;
"""
# also works
y = ['select * from y;', "-- still works"
# doesn't work
z = [
"""
select * from z;
""",
"""
-- nope, doesn't work
insert into z values (0, null);
"""

This works like a charm, the problem is that when I do this my vimrc plugins dont seem to work.
