showAggrOp :: AggrOp -> String Source
defaultSqlLiteral :: SqlGenerator -> Literal -> String Source
defaultSqlQuote :: SqlGenerator -> String -> String Source
quote :: String -> String Source
Quote a string and escape characters that need escaping We use Postgres "escape strings", i.e. strings prefixed with E, to ensure that escaping with backslash is valid.
binQuote :: ByteString -> String Source
Quote binary literals using Postgresql's hex format.
