Seen the description of string_to_array I would assume it is there to pair with array_to_string, which seems to its dual, as a way to [un]marshal arrays with potential nulls. OTOH regexp_split is not easily invertible and performs the type of operation you normally do with more free-form text, user input and the like. > I would suggest to put both into "String functions and operators" because > after all string_to_array() does more or less the same as > regexp_split_to_array() does.

Given the above I would certainly expect array_to_string in array functions. Then I would expect string_to_array next to it. And any regexp related function clustered with its siblings, either in the string page or ( in another manuals ) in its dedicated section.
