Well, as pcre stands for 'perl compatible re', I would guess it should
be exactly the same.
But the best answer you can get is testing itself by using postmap -q
with that regex pattern and a few test-lines.
I believe a regexp style pattern is almost the same, with only \s
replaced by [[:space:]]
See the pcre(7) and regex(7) manpages for the details.
