Using dollar-quotes means not having to escape your \d (which I
always find a bit of a hassle):
WHERE your_field ~ $re$\d{2}$$re$;
It's important to remember to use a tagged dollar quote (e.g., $re$)
if you're using $ as an anchor.
And with standard_conforming_strings on you don't even need to use
dollar-quotes:
test=# show standard_conforming_strings;
standard_conforming_strings
-----------------------------
on
(1 row)
test=# select 'foo33' ~ '\d{2}$';
?column?
----------
t
(1 row)
Dollar-quoting gets you around having to worry about what
standard_conforming_strings is set to, though.
