array_reverse()

Hi all

Before I go ahead and try to write a decent quality version: is there
any chance an array_reverse() function (in C) would be accepted into Pg
mainline? If not, I probably won't bother cleaning up my current
awful-hack quality module.

It's a slow operation to perform in SQL or PL/PgSQL even with 8.4's
array_agg(...) and generate_subscripts(...) and given how many languages
seem to provide built-in support it seems to be an operation people need
quite a bit.
