292 RELSEG_SIZE * BLCKSZ must be less than your OS' limit on file size.
293 This is often 2 GB or 4GB in a 32-bit operating system, unless you
294 have large file support enabled. By default, we make the limit 1 GB
295 to avoid any possible integer-overflow problems within the OS.

297 relation into more chunks than necessary, so it seems best to err
298 in the direction of a small limit.
