OR.. you can do this the easy/proper way with yum and simply do 'yum remove postresql' and let yum do the hard work for you. I'd also recommend using the repository file on dev.centos.org to let yum do the installing for you. There are a couple compat-libs packages you need to make postgresql work with php etc. -- Any sufficiently advanced technology is indistinguishable from magic. -Arthur C. Clarke
