Pyrseas provides utilities to describe a PostgreSQL database schema as YAML, to verify the schema against the same or a different database and to generate SQL that will modify the schema to match the YAML description.


  • Outputs a YAML/JSON description of a PostgreSQL database’s tables and other objects (metadata), suitable for storing in a version control repository
  • Generates SQL statements to modify a database so that it will match an input YAML/JSON specification
  • Generates an augmented YAML description of a PostgreSQL database from its catalogs and an augmentation specification.
