Perseas is a GitHub-based open-source organization that develops utilities to help with the management and maintenance of Postgres databases.
Our flagship project is Pyrseas. This provides a utility to create a YAML/JSON description of a Postgres database so that it can be stored and diff'ed in a version control repository. A second utility allows the YAML description to be compared to an actual Postgres database and to generate SQL data definition commands to synchronize the target database with the YAML.
