255 BLCKSZ must be a power of 2. The maximum possible value of BLCKSZ
256 is currently 2^15 (32768). This is determined by the 15-bit widths
257 of the lp_off and lp_len fields in ItemIdData (see

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