Backslash string-escaping incorrect? #17

For compatibility with systems which may have changed the default LIKE-clause escape-character, sometimes it will be specified explicitly:

    SELECT * FROM information_schema WHERE 
        table_name LIKE 'd\_%' ESCAPE '\'
        AND table_schema IN ('chapow_core')

Despite the syntax highlighting you may see above indicating there's an un-terminated string, you'll note from this SQL Fiddle that Postgres does not treat the backslash as an escape-character within the string, and therefore does not hit a syntax-error. This behavior may be different from generic SQL.

I'm happy to submit test and modifications using a patch or pull-request if you'll take it.

Cheers.
