NAME

       dblink_send_query - sends an async query to a remote database

SYNOPSIS

       dblink_send_query(text connname, text sql) returns int

DESCRIPTION

       dblink_send_query sends a query to be executed asynchronously, that is, without immediately waiting for
       the result. There must not be an async query already in progress on the connection.

       After successfully dispatching an async query, completion status can be checked with dblink_is_busy, and
       the results are ultimately collected with dblink_get_result. It is also possible to attempt to cancel an
       active async query using dblink_cancel_query.

ARGUMENTS

       connname
           Name of the connection to use.

       sql
           The SQL statement that you wish to execute in the remote database, for example select * from
           pg_class.

RETURN VALUE

       Returns 1 if the query was successfully dispatched, 0 otherwise.

EXAMPLES

           SELECT dblink_send_query('dtest1', 'SELECT * FROM foo WHERE f1 < 3');
