I do occasionally write some pl/pgSQL, and have at some points written a
lot of it. And most of it uses = instead of := , including all code
written during last 1.5 years. 

Once I found out that = works for assignment, i completely stopped
using := .I have treated := as "deprecated" for some time already.

So allowing only := for assignment would make me very sad .
