More specifically, Perl, Java and Python interpret \b as a backspace in the
Character class only (got that from the Regular Expression pocket reference)
but otherwise are word boundries. I am not entirely sure what the Character
class context is referring to but it does show that \b is interpreted
differently under different contexts. PostgreSQL may not have a way (or at
least a very good way) to make this distinction.

Any other thoughts?
