This reverts commit 9f984ba6d23dc6eecebf479ab1d3f2e550a4e9be. It was making the buildfarm unhappy, apparently setting client_min_messages in a regression test produces different output if log_statement='all'. Another issue is that I now suspect the bit sortsupport function was in fact not correct to call byteacmp(). Revert to investigate both of those issues.
