Commit8355a011a0was reverted inf05230752d, but this attempt is hopefully better-considered: we now pass the correct value to ExecOpenIndices, which should avoid the crash that we hit before. Amit Langote, reviewed by Simon Riggs and by me. Some final editing by me. Discussion: http://postgr.es/m/7ff1e8ec-dc39-96b1-7f47-ff5965dceeac@lab.ntt.co.jp
