Fix ATSimpleRecursion() to allow recursion from a foreign table.

2015年4月28日 19:25:00 +0000 (12:25 -0700)

This is necessary in view of the changes to allow foreign tables to be
full members of inheritance hierarchies, but I (tgl) unaccountably missed
it in commit cb1ca4d800621dcae67ca6c799006de99fa4f0a5.
