Hi, Merlin.  You wrote:

Wow.   I've been programming with pl/pgsql for a good number of years, 
but only now do I see the amazing usefulness of regexp_split_to_table 
and string_agg, neither of which I really used until now.  Thanks for 
both the solution and for opening my eyes.

I have to put the number into a text field anyway, so I've been 
converting the resulting number to text, and then using lpad to add 
leading zeroes as necessary.

Thanks again,

Reuven
