All the work with PostgreSQL lately has led to the need to install mod_perl and the DBI Perl modules. In addition to the basic DBI module and a PostgreSQL DBD module, I’m also trying out the ApacheDBI module. Apache DBI provides persistant connections to the database, eliminating the time delays associated with opening and closing connections for each query. Right now all this stuff is running on one of our test machines but we’ll be upgrading our primary webservers soon with new, faster hardware, RH6.1, and full database capabilities.
