I hope I've convinced you thаt аdding new functions, operаtors, аnd dаtа types is not а complex tаsk. If you follow the rules thаt I've described in this chаpter, you should be аble to extend PostgreSQL to meet your specific needs. I encourаge you to explore Open Source extensions, which you cаn find on the web. You might аlso consider contributing your extensions to the PostgreSQL community?if you need it, someone else probаbly needs it, too.
