Thanks for saving me some time, as it would have taken me quite a while
to figure that out.

I'll adjust the constraint so that good strings aren't rejected. Which
was my immediate problem. I'm not that worried about bad strings getting
added, since the data also gets checked before trying to add it to
the database.

One thing I would suggest is documenting this limitation under:
https://www.postgresql.org/docs/9.6/static/functions-matching.html#FUNCTIONS-POSIX-REGEXP

I might have missed it, but I did try reading that section to see if I was
doing something wrong before asking on the list. In particular I would
expect this limitation to be noted under:
9.7.3.6. Limits and Compatibility
