Hi Nikhil,
Many thanks for working on this. I proposed a similar patch some time
ago [1] but the overall feedback was somewhat mixed so I choose to
focus on something else. Thanks for peeking this up.

Did you have a chance to familiarize yourself with the corresponding
discussion [1] and probably the previous threads? Particularly it was
pointed out that dictionaries should be built automatically during
VACUUM. We also discussed a special syntax for the feature, besides
other things.
