PostgreSQL's system catalogs store everything there is to know about the server and the structures contained in its databases.
Postgres Compare uses the system catalogs to determine the changes that have been made. The differences produce the CREATE, ALTER
and DELETE SQL that ensure the database is up to date.
Postgres Compare takes a snapshot of the server and stores it locally so you can easily keep track of changes or compare against old versions.
Connections, comparisons and deployment scripts too are stored for re-use and reporting purposes.
As an example imagine you have changed the datatype of a column in your test environment. Postgres Compare looks at the
pg_attribute system catalog and detects that the column has been changed compared to production.
You go ahead and generate a deployment script that saves you time and ensures you don't miss anything!
