Pyrseas provides a framework and utilities to upgrade and maintain a relational database. It currently includes the dbtoyaml utility to create a YAML description of a PostgreSQL database's tables, and the yamltodb utility to generate SQL statements to modify a database to match an input YAML specification. It also aims to develop data administration tools to supplement an agile database development process.

0.4.1

This is a maintenance release. The initial SET search_path is persistent. Exclusion of PG internal schemas in various queries has been fixed. Generation of COMMENTs with single quotes in the text has been fixed. For inherited tables, this release will only generate constraints that are defined locally. Generation of ALTER TABLE ADD/DROP COLUMN when input columns are in a different order than the original has been corrected (issue #8). Support has been added for PG 9.1 (a description for the PL/pgSQL language has been added).

CONVERSIONs, dynamically loaded C language functions, OPERATORs, OPERATOR CLASSes and OPERATOR FAMILies, and composite and base TYPEs. Other changes include a cleanup and enhancement of the documentation, removal of redundant methods, and the use of obj_description/col_description functions instead of querying pg_description directly.
