Actually, I'm not sure :) As I've mentioned, python/java/perl do as I
expected, postgres on the other hand doesn't. If \b was the backspace,
then I'd have trouble with '+mario test', and that one seems to be OK.
I also tried doublebackslashing, all the same.
So, I guess it's obvious that postgres doesn't treat regular expressions
the same way as java/perl/pyton/php/awk/sed do...
