## 53.36. `pg_parameter_acl`

The catalog `pg_parameter_acl` records configuration parameters for which privileges have been granted to one or more roles. No entry is made for parameters that have default privileges.

Unlike most system catalogs, `pg_parameter_acl` is shared across all databases of a cluster: there is only one copy of `pg_parameter_acl` per cluster, not one per database.
