Variants

InvalidByteSequence(u8)

v7.39 (round 773, F31 J3) — an E-string’s byte escapes decoded to an invalid UTF-8 sequence. PG decodes \NNN / \xHH as BYTES and validates the whole literal (E'\303\251' is é; E'\777' is byte 0xFF and refuses); the old decoder mapped each byte to its Latin-1 codepoint, silently mangling every multi-byte sequence.

UnknownChar(char)

UnterminatedString

UnterminatedQuotedIdent

UnterminatedBlockComment

BadNumber(String)

TrailingJunkAfterNumber(String)

v7.39 (round 184) — a numeric literal followed directly by an identifier character (12__34, 123_, 1.5_, 123abc). PG rejects at scan time; pre-r184 SPG silently lexed the number and let the tail become a column alias (SELECT 12__34 → 12).

InvalidRadixLiteral(&'static str, String)

v7.39 (round 184) — a radix prefix with no digits (0x, 0o, 0b); pre-r184 the 0 lexed alone and the letter aliased. Payload: (radix-name, literal-text).

InvalidUnicodeEscape
