Definition PG 18

\dd[Sx] [ pattern ]

Shows the descriptions of objects of type constraint, operator class, operator family, rule, and trigger. All other comments may be viewed by the respective backslash commands for those object types.

\dd displays descriptions for objects matching the pattern, or of visible objects of the appropriate type if no argument is given. But in either case, only objects that have a description are listed. By default, only user-created objects are shown; supply a pattern or the S modifier to include system objects. If x is appended to the command name, the results are displayed in expanded mode.

Descriptions for objects can be created with the COMMENT SQL command.
