pgquarrel - Compares PostgreSQL database schemas (DDL)
- Description:
pgquarrel is a program that compares PostgreSQL database schemas (DDL).
Given two database connections, it output a file that represent the
difference between schemas. It means that if you run the output file into
the target database, it'll have the same schema as the source database.
The main use case is to deploy database changes into testing, staging or
production environment.
pgquarrel does not rely on another tool (such as pg_dump) instead it connects
directly to PostgreSQL server, obtain meta data from catalog, compare objects
and output the commands necessary to turn target database into source
database.
