The thing to do here is leave a blank line between each one.  You can
also put a line of dashes before and after the comment (see many
examples elsewhere in the source tree) to force pgindent to leave that
section completely untouched, but I think that this sort of list looks
better with blank lines anyway, so I'd go for that solution.

Same idea here.
