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 a database instance. That is, there is only one PG_SHDESCRIPTION for each instance, not for each database.

**Table 1** PG_SHDESCRIPTION columns
Name	Type	Reference	Description
objoid	oid	Any OID column	OID of the object that this description pertains to.
classoid	oid	oid in PG_CLASS	OID of the system catalog where the object appears.
description	text	-	Arbitrary text that serves as the description of the object.
