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

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