SYNOPSIS

       dblink_cancel_query(text connname) returns text

DESCRIPTION

           Note

           The following description applies only to Postgres-XC

       dblink module has not been tested with Postges-XC yet. Although there're no reason that dblink does not
       run in Postgres-XC, the development team leaves the test and the use of this module entirely to users.

       This section is identical to the corresponding PostgreSQL reference manual.

           Note

           The following description applies only to PostgreSQL

       dblink_cancel_query attempts to cancel any query that is in progress on the named connection. Note that
       this is not certain to succeed (since, for example, the remote query might already have finished). A
       cancel request simply improves the odds that the query will fail soon. You must still complete the normal
       query protocol, for example by calling dblink_get_result.
