This patch incurs a compiler warning, which probably is quite simple to fix:

heapam.c: In function ‘heap_multi_insert’:
heapam.c:2349:4: error: ‘recptr’ may be used uninitialized in this function [-Werror=maybe-uninitialized]
    visibilitymap_set(relation, BufferGetBlockNumber(buffer), buffer,
    ^
heapam.c:2136:14: note: ‘recptr’ was declared here
   XLogRecPtr recptr;
              ^

Please fix and submit a new version, I'm marking the entry Waiting on Author in
the meantime.

cheers ./daniel
