It appeared to me that it fetches it in order to return it in an
application inquiry function [1]. So to really gauge the damage,
you'd have to find out how many PHP applications pay attention
to the "array dims" field of pg_meta_data(). Maybe it's a trivial
number, or maybe not --- I didn't have the energy to search.
