Actually, that's not quite correct. Spencer's latest regexp(3) was integrated into PostgreSQL 7.4 to provide wide-byte regexp support (released on 2003-11-17). Last I checked, it was being used regularly and with good success as it's gotten a good ten months of production use. :) From the PostgreSQL 7.4 release notes: "Faster and more powerful regular expression code "The entire regular expression module has been replaced with a new version by Henry Spencer, originally written for Tcl. The code greatly improves performance and supports several flavors of regular expressions." -sc -- Sean Chittenden
