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 performs a similar function for descriptions involving objects within a single database.

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

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