Subject: pgsql: Unicode case mapping tables and functions.
Date: Thu, 07 Mar 2024 19:18:11 +0000
Message-ID: <E1riJFq-002aP8-QF@gemulon.postgresql.org> (raw)
Unicode case mapping tables and functions.
Implements Unicode simple case mapping, in which all code points map
to exactly one other code point unconditionally.
These tables are generated from UnicodeData.txt, which is already
being used by other infrastructure in src/common/unicode. The tables
are checked into the source tree, so they only need to be regenerated
when we update the Unicode version.
In preparation for the builtin collation provider, and possibly useful
for other callers.
