That allows *setting* REINDEXOPT_VERBOSE, but doesn't *unset* it if someone runs (VERBOSE OFF). So I kept the bools like Michael originally had rather than writing "else: params.options &= ~REINDEXOPT_VERBOSE" > See also attached txt file with diff (I wonder can I trick cfbot this way, > so it does not apply the diff). Yes, I think that works :) I believe it looks for *.diff and *.patch. > + int options; /* bitmask of lowlevel REINDEXOPT_* */ > > I would prefer if the comment says '/* bitmask of ReindexOption */' as in > the VacuumOptions, since citing the exact enum type make it easier to > navigate source code. Yes, thanks. This also fixes some minor formatting and rebase issues, including broken doc/. -- Justin
