CLASS="COMMAND"
>CREATE USER MAPPING</TT
> defines a mapping of a user
to a foreign server. A user mapping typically encapsulates
connection information that a foreign-data wrapper uses together
with the information encapsulated by a foreign server to access an
external data resource.
</P
><P
> The owner of a foreign server can create user mappings for that
server for any user. Also, a user can create a user mapping for
his own user name if <TT
CLASS="LITERAL"

been granted to the user.
