Hi hackers, While I was working on my empty array patch I was frequently irritated by the absence of an array_length(anyarray). The same goes for array_upper and array_lower. Most of the time when I work with arrays, they are 1-D, and it's inelegant to having to specify which dimension I mean when there is only one to choose from.
The question I have (and would appreciate your input on) is how such single-argument variants should behave when operating on an array with multiple dimensions? I see a few different options: a) throw an error like "Dimension argument is required for multiple dimension arrays" b) assume the user means the final (innermost) dimension c) assume the user means the first (outermost) dimension My inclination is towards (c) but I don't use multi-D arrays in postgres in the field. Opinions? Cheers, BJ -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
