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.
