In Perl at least, \b is a word boundary. In PostgreSQL (and probably
Tcl as well) it's a backslash AFAICT.
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?
