Allows executing the CHECKPOINT command.

Allows users with CREATE permission on the database to issue CREATE SUBSCRIPTION.

Membership consists, implicitly, of the current database owner. Like any role, it can own objects or receive grants of access privileges. Consequently, once pg_database_owner has rights within a template database, each owner of a database instantiated from that template will exercise those rights. pg_database_owner cannot be a member of any role, and it cannot have non-implicit members. Initially, this role owns the public schema, so each database owner governs local use of the schema.

Allows executing VACUUM, ANALYZE, CLUSTER, REFRESH MATERIALIZED VIEW, REINDEX, and LOCK TABLE on all relations, as if having MAINTAIN rights on those objects, even without having it explicitly.

pg_read_all_data allows reading all data (tables, views, sequences), as if having SELECT rights on those objects, and USAGE rights on all schemas, even without having it explicitly. This role does not have the role attribute BYPASSRLS set. If RLS is being used, an administrator may wish to set BYPASSRLS on roles which this role is GRANTed to.

pg_write_all_data allows writing all data (tables, views, sequences), as if having INSERT, UPDATE, and DELETE rights on those objects, and USAGE rights on all schemas, even without having it explicitly. This role does not have the role attribute BYPASSRLS set. If RLS is being used, an administrator may wish to set BYPASSRLS on roles which this role is GRANTed to.

These roles are intended to allow administrators to easily configure a role for the purpose of monitoring the database server. They grant a set of common privileges allowing the role to read various useful configuration settings, statistics, and other system information normally restricted to superusers.

pg_read_all_settings allows reading all configuration variables, even those normally visible only to superusers.

pg_read_all_stats allows reading all pg_stat_* views and use various statistics related extensions, even those normally visible only to superusers.

pg_stat_scan_tables allows executing monitoring functions that may take ACCESS SHARE locks on tables, potentially for a long time.

pg_monitor allows reading/executing various monitoring views and functions. This role is a member of pg_read_all_settings, pg_read_all_stats and pg_stat_scan_tables.

These roles are intended to allow administrators to have trusted, but non-superuser, roles which are able to access files and run programs on the database server as the user the database runs as. As these roles are able to access any file on the server file system, they bypass all database-level permission checks when accessing files directly and they could be used to gain superuser-level access, therefore great care should be taken when granting these roles to users.

pg_read_server_files allows reading files from any location the database can access on the server with COPY and other file-access functions.

pg_write_server_files allows writing to files in any location the database can access on the server with COPY any other file-access functions.

pg_execute_server_program allows executing programs on the database server as the user the database runs as with COPY and other functions which allow executing a server-side program.

Allows signaling another backend to cancel a query or terminate its session. A user granted this role cannot however send signals to a backend owned by a superuser. See Section 9.28.2.

Allows use of connection slots reserved via reserved_connections.
