AC_DEFINE_UNQUOTED([RELSEG_SIZE], ${RELSEG_SIZE}, [
RELSEG_SIZE is the maximum number of blocks allowed in one disk file.
Thus, the maximum size of a single file is RELSEG_SIZE * BLCKSZ;
relations bigger than that are divided into multiple files.
RELSEG_SIZE * BLCKSZ must be less than your OS' limit on file size.
This is often 2 GB or 4GB in a 32-bit operating system, unless you
have large file support enabled. By default, we make the limit 1 GB
to avoid any possible integer-overflow problems within the OS.
A limit smaller than necessary only means we divide a large
relation into more chunks than necessary, so it seems best to err
in the direction of a small limit.
A power-of-2 value is recommended to save a few cycles in md.c,
but is not absolutely required.
