gcc 8 has started emitting some warnings that are largely useless for our purposes, particularly since they complain about code following the project-standard coding convention that path names are assumed to be shorter than MAXPGPATH. Even if we make the effort to remove that assumption in some future release, the changes wouldn't get back-patched. Hence, just suppress these warnings, on compilers that have these switches. Backpatch to all supported branches. Discussion: https://postgr.es/m/1524563856.26306.9.camel@gunduz.org

A limit smaller than necessary only means we divide a large

relation into more chunks than necessary, so it seems best to err

A power-of-2 value is recommended to save a few cycles in md.c,
