Uhh...

#define MaxHeapAttributeNumber    1600    /* 8 * 200 */

Did you modify that?

(The back of my envelope says that on 64bit, the largest usable t_hoff
would be 248, of which 23 is fixed overhead leaving 225 as the max null
bitmap size, giving a hard limit of 1800 for MaxTupleAttributeNumber and
1799 for MaxHeapAttributeNumber. And the concerns expressed in the
comments above those #defines would obviously apply.)
