260 reduce the need to have large tuples, since fields can be spread
261 across multiple tuples).
263 BLCKSZ must be a power of 2. The maximum possible value of BLCKSZ
264 is currently 2^15 (32768). This is determined by the 15-bit widths
265 of the lp_off and lp_len fields in ItemIdData (see

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