postgresql-postgis: support for geographic objects
postgresql-12-pgrouting: routing and other network analysis functionality to PostGIS
postgresql-contrib: advanced object-relational database management system that supports an extended subset of the SQL standard, including transactions, foreign keys, subqueries, triggers, and user-defined types and functions
postgresql-12-pg-qualstats: PostgreSQL extension keeping statistics on predicates found in WHERE statements and JOIN clauses. This is useful if you want to be able to analyze what are the most-often executed quals (predicates) on your database
These modules still need a "CREATE" in the runtime PSQL service which is an optional task for the consumer of this image.
