Log message:
    Bring SIMILAR TO and SUBSTRING into some semblance of conformance with
    the SQL99 standard.  (I'm not sure that the character-class features are
    quite right, but that can be fixed later.)  Document SQL99 and POSIX
    regexps as being different features; provide variants of SUBSTRING for
    each.
