+.SH "NAME"
+dblink_error_message \- gets last error message on the named connection
+.SH "SYNOPSIS"
+.sp
+.nf
+dblink_error_message(text connname) returns text
+.fi
+.SH "DESCRIPTION"
+.PP
+\fBdblink_error_message\fR
+fetches the most recent remote error message for a given connection\&.
+.SH "ARGUMENTS"
+.PP
+\fIconnname\fR
+.RS 4
+Name of the connection to use\&.
+.RE
+.SH "RETURN VALUE"
+.PP
+Returns last error message, or
+OK
+if there has been no error in this connection\&.
+.SH "NOTES"
+.PP
+When asynchronous queries are initiated by
+\fBdblink_send_query\fR, the error message associated with the connection might not get updated until the server\*(Aqs response message is consumed\&. This typically means that
+\fBdblink_is_busy\fR
+or
+\fBdblink_get_result\fR
+should be called prior to
+\fBdblink_error_message\fR, so that any error generated by the asynchronous query will be visible\&.
