I have done an extensive comparison between MySQL's support for regexp
and Postresql's and, frankly, there is no comparison.  The support in
Postgresql is far greater than in MySQL.  This is not a flame.  It is
intended to help anyone choosing between the two programs.

The best example I can present is the regexp_split_to_table function
in Postgres.  I use it all the time.  It is enormously convenient.
Anyone analyzing text is ecstatic to have such a powerful function
readily available.

This is a qualitative difference.
