user_mapping_options

user_mapping_options

The user_mapping_options view contains all of the options defined for user mappings in the current database. Greenplum Database displays only those user mappings to which the current user has access (by way of being the owner or having some privilege).

Table 1. user_mapping_options
column type references description
authorization_identifier sql_identifier   Name of the user being mapped, or PUBLIC if the mapping is public.
foreign_server_catalog sql_identifier   Name of the database in which the foreign server used by this mapping is defined (always the current database).
foreign_server_name sql_identifier   Name of the foreign server used by this mapping.
option_name sql_identifier   Name of an option.
option_value character_data   Value of the option. This column will display null unless:
  • The current user is the user being mapped.
  • The mapping is for PUBLIC and the current user is the foreign server owner.
  • The current user is a superuser.

The intent is to protect password information stored as a user mapping option.
