The easiest way that I can think of is using plpython (although for those so
inclined, I imagine plperl might do the job about as easily):
create function nelem(text) returns int as '
return len(args[0].split('',''))
' language 'plpython';
That should work very quickly compared with any loop or recursion. The first
call might take a moment to load the python interpreter, but after that if
should be fine.
