# `HephaestusEcto.Migrations.Postgres`
[🔗](https://github.com/lucas-stellet/hephaestus_ecto/blob/v0.3.0/lib/hephaestus_ecto/migrations/postgres.ex#L1)

PostgreSQL migration orchestrator for `HephaestusEcto`.

This module coordinates versioned migration modules (`V01`, `V02`, and so on) and keeps the
applied schema version in a comment on the `workflow_instances` table. The public
`HephaestusEcto.Migration` module delegates here for all `up/1`, `down/1`, and
`migrated_version/1` calls.

The orchestrator pattern keeps each schema change isolated in its own module while still
exposing a stable, version-aware API to host applications.

# `current_version`
