System catalog

This topic provides an overview of builtin objects, how they relate, and how they can be queried.

The default database

Every GlareDB deployment is initialized with a default database. This database cannot be dropped. Schemas, views, and external tables can be created within this database.

The default database contains three schemas providing information about a running system.

  • glare_catalog: A schema containing internal information about the deployment.
  • pg_catalog: A set of views on top of glare_catalog that aims to provide Postgres compatibility.
  • information_schema: A set of views on top of glare_catalog for providing standard information schema compatibility.
