It looks like you are neglecting to allow for the fact that backslash is an escape character both at the string-literal level and at the regex-pattern level. Therefore you must write twice as many backslashes as you normally would write in a regex pattern. In particular, '\\\\' to match a literal backslash. regards, tom lane
