The pg_namespace system catalog table stores namespaces. A namespace is the structure underlying SQL schemas: each namespace can have a separate collection of relations, types, etc. without name conflicts.
| column | type | references | description |
|---|---|---|---|
oid | oid | Row identifier (hidden attribute; must be explicitly selected) | |
nspname | name | Name of the namespace | |
nspowner | oid | pg_authid.oid | Owner of the namespace |
nspacl | ARRAY | Access privileges as given by GRANT and REVOKE |
Apache Cloudberry is an effort undergoing incubation at The Apache Software Foundation (ASF), sponsored by the Apache Incubator. Incubation is required of all newly accepted projects until a further review indicates that the infrastructure, communications, and decision making process have stabilized in a manner consistent with other successful ASF projects. While incubation status is not necessarily a reflection of the completeness or stability of the code, it does indicate that the project has yet to be fully endorsed by the ASF.
