I sent two emails last night, one to -patches and one to -hackers. Neither
seems to have come through. Has anyone else seen them?
On -patches I posted an updated patch that was functionally a noop but changed
the macro api to SETVARSIZE(). It also replaced the VARATT_SIZE and
VARATT_DATA macros with VARSIZE and VARDATA, changed inet to call detoast, and
changed arrays, inet, geometric data types and a handful of others to use
SET_VARSIZE instead of accessing a struct member directly.
On -hackers I reposted Tom's email where he proposed two sets of bitpatterns
with tradeoffs and also included an additional one that was the second of his
with the 2-byte cases removed.
In it I said that removing the 2-byte cases had no advantages but actually
since then I've thought of one. It makes the toaster code simpler since it can
just set a bit in the four-byte header just as it does now. It doesn't have to
worry about converting to a 2-byte header.
