(1) Please do not post HTML.
(2) Your example fails instantly with
ERROR: a column definition list is required for functions returning "record"
I'm prepared to believe that there's a loop in crosstab() that fails to
check for interrupts reasonably often, but it's not obvious where. You
need to provide a complete working test case if you want the problem
investigated.
