Thanks for the fix!
I did the same, and it does not help in my case. FWIW, the regexp I'm matching is: <pre .*?>(.*?)</pre> (yes, the production system has already been fixed to use a smarter regexp that solves the same problem) The text is about 180Kb. PostgreSQL takes ~40 seconds without the patch, ~36 seconds with it, to extract the match from it. Perl takes 0.016 seconds. -- Magnus Hagander Me: http://www.hagander.net/ Work: http://www.redpill-linpro.com/ -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
