Like a painter, you must know when to stop painting. This is a real dilemma all painters face, especially when dealing with watercolor. If anyone has tried painting here, you know exactly the problem - how do you know you're done? It applies to writing and music as well, but it is more evident in visual arts than any other field.
I wish there was a Postgres branch that took previous version and then just applied optimizations and bugfixes. No more.
