I love PostgreSQL COMMENT. I built a prototype app for a buddy with Supabase and added a COMMENT to every table.

I hate it. I used it to have carefully curated metadata (sources etc) to my collection of tens of tables, and someone else took backup/restore of the database and all this was lost.

with supabase it is almost essential. But adding comments with migrations is somewhat tedious, unless you're writing actual sql. Like, you know, with supabase.
