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

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