I don't think anyone asked for the start position and length in the result of 
regexp_split().  The result should be an array of text.  That is what Perl et 
al. do.

As for the regexp_matches() function, it seems to me that it returns too much 
information at once.  What is the use case for getting all of prematch, 
fullmatch, matches, and postmatch in one call?
