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.

escape :: Char -> String Source #

Escape characters that need escaping

binQuote :: ByteString -> String Source #

Quote binary literals using Postgresql's hex format.
