Because plpgsql's scanner uses %option case-insensitive, flex's results could
theoretically vary depending on what the compile-time locale setting is.Hence, force it to see LC_CTYPE=C to ensure consistent build results.(It's likely that this makes no difference in practice, since ourspecification for "identifier" surely includes both ends of any possibleuppercase/lowercase pair anyway. But it should silence warnings aboutambiguous character classes that are reported by some buildfarm members.)
