241 reduce the need to have large tuples, since fields can be spread

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

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

278 but is not absolutely required.
