+[pgschema](https://github.com/pgschema/pgschema) is a new CLI-based tool, written in Go. It features a terraform-like declarative schema migration workflow:
+
+- **Dump** a Postgres schema in a developer-friendly format with support for all common objects
+- **Edit** a schema to the desired state
+- **Plan** a schema migration by comparing desired state with current database state
+- **Apply** a schema migration with concurrent change detection, transaction-adaptive execution, and lock timeout control
