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

289 This is often 2 GB or 4GB in a 32-bit operating system, unless you
290 have large file support enabled. By default, we make the limit 1 GB
291 to avoid any possible integer-overflow problems within the OS.
292 A limit smaller than necessary only means we divide a large
293 relation into more chunks than necessary, so it seems best to err
294 in the direction of a small limit.
