This patch fixes subtract_integer_from_now on 32-bit platforms, improves error handling and adds some basic tests. subtract_integer_from_now would trigger an assert when called on a hypertable without integer time dimension (found by sqlsmith). Additionally subtract_integer_from_now would segfault when called on a hypertable without partitioning dimensions.
