I am not excited about the idea of documenting functions twice; that would
almost certainly lead to the redundant entries getting out of sync.
We could possibly decide that string_to_array and array_to_string are
primarily string functions not array functions, and just move them to
the string-functions page.
Another possibility is to just add cross-references to the
string-functions page, like the existing one for string_agg().
But I think I like the first idea better, in view of
regexp_string_to_array already being here.
