dblink_is_busy

Description

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.

dblink_is_busy tests whether an async query is in progress.

Arguments

Return Value

Returns 1 if connection is busy, 0 if it is not busy. If this function returns 0, it is guaranteed that dblink_get_result will not block.

Examples

SELECT dblink_is_busy('dtest1');
