52.49. pg_shdescription #

   The catalog pg_shdescription stores optional descriptions (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.
