268 is currently 2^15 (32768). This is determined by the 15-bit widths

291 relations bigger than that are divided into multiple files.
293 RELSEG_SIZE * BLCKSZ must be less than your OS' limit on file size.
294 This is often 2 GB or 4GB in a 32-bit operating system, unless you
295 have large file support enabled. By default, we make the limit 1 GB
296 to avoid any possible integer-overflow problems within the OS.
297 A limit smaller than necessary only means we divide a large
298 relation into more chunks than necessary, so it seems best to err
299 in the direction of a small limit.
