I have a documentation follow-up to this. It seems that these new
functions are almost a de facto standard, whereas the SQL-standard
functions are not implemented anywhere. I propose the attached patch to
update the subsection in the pattern-matching section to give more
detail on this and suggest equivalent functions among these newly added
ones. What do you think?
