PG_SHDESCRIPTION

PG_SHDESCRIPTION records optional comments for shared database objects. Descriptions can be manipulated with the COMMENT command and viewed with psql's \d commands.

See also PG_DESCRIPTION, which provides a similar function for descriptions involving objects within a single database.

Unlike most system catalogs, PG_SHDESCRIPTION is shared across all databases in the system. There is only one copy of PG_SHDESCRIPTION in the openGauss system, not one per database.
