The previous system had configure put the value into the makefiles and then have the makefiles pass them to the build of pg_config. That was put in place when pg_config was a shell script. We can simplify that by having configure put the value into pg_config.h directly. This also makes the standard build system match how the MSVC build system already does it.

RELSEG_SIZE * BLCKSZ must be less than your OS' limit on file size.

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,
