8d48e6a724 uses RELKIND_ constants when building the query, but
did not include the header defining them. On 10+ this header is already
included, but on 9.6 and earlier it was missing. It compiles just fine,
but then fails during execution
ERROR: column "relkind_relation" does not exist
Fix by adding the necessary header file, and backpatch to 9.4-.
Backpatch-to: 9.4-
