Re: ALTER TABLE ... ALTER COLUMN ... SET DISTINCT - Mailing list pgsql-hackers

Are there plans to make a small follow-up patch to make
CREATE UNIQUE INDEX on one column
(and variants in CREATE TABLE ... PRIMARY KEY) automatically do
SET STATISTICS DISTINCT?

It might not be as perfect a solution as teaching the planner to know 
about unique indexes, but it is better than nothing.

Good work!
