What Does a Database Migration Mean?
I’ve been building a personal project with Codex. Doesn’t matter what it does — the relevant part is that it needs a server, and for that Codex told me to use Supabase. Fine. I have no opinions about backend-as-a-service, I just want something that stores rows and doesn’t make me think about it. Then it created a jobs table and put it in a file called supabase/migrations/20260821143210_create_jobs.sql: create table jobs ( id uuid primary key default gen_random_uuid(), title text not null, created_at timestamptz not null default now() ); alter table jobs enable row level security; Fine....
