Various bugs can cause crashes, so don't use that function before ICU 53. It will fall back to the code path used for other encodings. Since we now tie the function availability to an ICU version, we don't need the configure test anymore. That also resolves the issue that the test result was previously hardcoded for Windows. researched by Daniel Verite <daniel@manitou-mail.org>, Peter Geoghegan <pg@bowt.ie>, Tom Lane <tgl@sss.pgh.pa.us> Discussion: https://www.postgresql.org/message-id/flat/f1438ec6-22aa-4029-9a3b-26f79d330e72%40manitou-mail.org

RELSEG_SIZE * BLCKSZ must be less than your OS' limit on file size.

A limit smaller than necessary only means we divide a large

relation into more chunks than necessary, so it seems best to err

A power-of-2 value is recommended to save a few cycles in md.c,
