X-Git-Url: http://these/git/sneer-club-logo.svg?a=commitdiff_plain;h=1c9f0c2bed51eb240d8514d28993c5516c019afc;p=lemmy.git

Add db index for post.url column (#2929)

* Add db index for post.url column

As mentioned in https://github.com/LemmyNet/lemmy/issues/2877#issuecomment-1576439829

Not sure if its preferable to do this, or make a combined index
which includes post.nsfw, post.removed, post.deleted

* remove unique
