Version 1 of the core pgflow schema.

The SQL bundle at priv/pgflow_core/sql/versions/v01/v01_up.sql is vendored from the upstream pgflow-dev/pgflow Postgres SQL migrations. See v01_manifest.json for the pinned upstream commit SHA and the file list consumed at mint time.

V01 is frozen. When upstream ships new core SQL, it becomes a new V02 delta — V01 is never rewritten, otherwise deployments already on V01 would silently diverge from the current bundle.

Four categories of statements are stripped during sync because they require Supabase-specific infrastructure:

• CREATE SCHEMA "pgmq" / CREATE EXTENSION "pgmq" — pgmq is installed SQL-only before this migration runs (via mix pgflow.gen.pgmq_migration).
• CREATE EXTENSION "pg_net" — Supabase-only HTTP extension; pgflow Elixir bindings make HTTP calls from Elixir, not from SQL.
• Functions that reference net.http_post — depend on pg_net.
