I thought it would be interesting to see if any differences
in *where* matches occur not only *what* matches.
I've compared the output from regexp_positions()
between REL_13_STABLE and HEAD.
I'm happy to report no differences were found,
except some new expected
invalid regular expression: invalid character range
errors due to the fixes.
This time I also ran into the
(["'`])(?:\\\1|.)*?\1
pattern due to using the flags,
which caused a timeout on REL_13_STABLE,
but the same pattern is fast on HEAD.
All good.
