PG_SHDESCRIPTION

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

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

PG_SHDESCRIPTION is shared among all databases of cluster. That is, there is only one PG_SHDESCRIPTION for each cluster, not for each database.

**Table 1** PG_SHDESCRIPTION columns
Name	Type	Reference	Description
objoid	oid	Any OID column	OID of the described object.
classoid	oid	OID in PG_CLASS	OID of the system catalog where the object appears.
description	text	-	Description of the object.
