+.SH "NAME"
+dblink_send_query \- sends an async query to a remote database
+.SH "SYNOPSIS"
+.sp
+.nf
+dblink_send_query(text connname, text sql) returns int
+.fi
+.SH "DESCRIPTION"
+.PP
+\fBdblink_send_query\fR
+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\&.
+.PP
+After successfully dispatching an async query, completion status can be checked with
+\fBdblink_is_busy\fR, and the results are ultimately collected with
+\fBdblink_get_result\fR\&. It is also possible to attempt to cancel an active async query using
+\fBdblink_cancel_query\fR\&.
+.SH "ARGUMENTS"
+.PP
+\fIconnname\fR
+.RS 4
+Name of the connection to use\&.
+.RE
+.PP
+\fIsql\fR
+.RS 4
+The SQL statement that you wish to execute in the remote database, for example
+select * from pg_class\&.
+.RE
+.SH "RETURN VALUE"
+.PP
+Returns 1 if the query was successfully dispatched, 0 otherwise\&.
