Thank you! (Slapping head)
Your regexp seems to do the trick.

have created a custom type as a domain based on text, which adds
a check constraint using a regexp to limit it to containing
digits and '.'. However I am finding I can add values with other
characters to a column of this type. Is this to be expected for
some reason?
Or alternately, did I define the constraint wrong somehow? It is
defined thus:
CREATE DOMAIN hierpath AS text
CHECK(
VALUE ~ '[0-9.]+'
);
Checking the docs I'm pretty sure the '.' doesn't need escaping
but I also tried a test leaving it out ( '[0-9]+') and the
result is the same. It lets me store letters in a column defined
to be of this type.
The version() function tells me
"PostgreSQL 9.4.5 on x86_64-unknown-linux-gnu, compiled by gcc
(Ubuntu 4.8.2-19ubuntu1) 4.8.2, 64-bit"
Thanks,

I think you regexp is
too weak. So long as the value has a digit or period, it's
good.
'^[0-9.]+$' might work
