: I think maybe what Ben was referring to was that Spencer has released
: an updated version of his regexp library that doesn't penalize wide
: character locales. I believe our current one performs terribly on
: everything but one byte character sets, whereas the newer Spencer
: library performs as well as one could hope with wide characters. The
: PostgreSQL group did some testing and found Spencers library to be the
: fastest wide character regexp engine while still maintaining very good
: levels of performance for single byte character sets. You'll have to
: check the PostgreSQL archives for details: it's been two years since
: that change was committed to their tree. -sc
As well as a number of other fixes from NetBSD and OpenBSD. I'm
pretty sure Ben doesn't care too much about wide character support...
