Since 2007, I've been one of the core developers of the Evergreen library system (http://evergreen-ils.org) . As a systems librarian at Laurentian University, I'm a tad obsessed with storing, retrieving, and linking data. With 15 years of experience with relational databases, PostgreSQL is the one for me (and I think it might be the right solution for you, too)!
I enjoy learning and introducing people to new technology, so I founded Google Developer Group Sudbury (http://gdgsudbury.ca) in 2012.
