Lovable Cloud to Supabase: Migration Path and Real Errors

Recreate a Postgres schema without pg_dump

No shell, no Postgres binary, no pg_dump. You can still rebuild a schema by reading the system catalogs and emitting CREATE statements in dependency order.

Fixing Supabase IPv6 connection failures (ENETUNREACH)

The direct db.<ref>.supabase.co host resolves to IPv6. On an IPv4-only network you get connect ENETUNREACH. The pooler host answers on IPv4 — here is the switch.

Migrate Supabase auth users without forcing a password reset

Supabase's admin API cannot set a bcrypt hash, so recreating users there forces a password reset. Insert into auth.users directly and keep every login working.

Migrate a Lovable Cloud project to your own Supabase

Lovable Cloud is a real Supabase Postgres backend. Here is what moves to a project you own, in what order, and the exact errors you hit if you get the order wrong.
