The PostgreSQL service type in PostgreSQL's own terms: databases, their schemas, the schemas' tables and views and the tables' columns, with access types that map to PostgreSQL's privileges, and row filters that become row security policies. Lookups read the catalogs of each database through PostgreSQL's own JDBC driver, from one server or the next when one cannot be reached, signing in with a password or a TLS client certificate. Packaged as a plugin directory ...

Loads service type plugins: built-in ones from the classpath, external ones from the plugins directory, each in its own class loader
