Ordering of arrays - Mailing list pgsql-sql

A question about arrays.

Is iit possible to reverse an array array?

for example

regexp_split_to_array(/srv/progs/programs/Aliens/The_Aliens_1_ens_envsc2_envsc2.mp4,'('/|\.)'), which splits on either / or . to extract fileparts

It would be useful to be able to have the array returned reversed, so rather than having to use cardinality(array)-1 I have a reversed array and say arr[1]

Also  it seems impossible to get a reverse slice (returns null array)

thanks
