304 RELSEG_SIZE * BLCKSZ must be less than your OS' limit on file size.
305 This is often 2 GB or 4GB in a 32-bit operating system, unless you
306 have large file support enabled. By default, we make the limit 1 GB
307 to avoid any possible integer-overflow problems within the OS.
308 A limit smaller than necessary only means we divide a large
309 relation into more chunks than necessary, so it seems best to err
310 in the direction of a small limit.
