DBLINK_ERROR_MESSAGE(3)           PostgreSQL 12.3 Documentation           DBLINK_ERROR_MESSAGE(3)



NAME
       dblink_error_message - gets last error message on the named connection

SYNOPSIS
       dblink_error_message(text connname) returns text

DESCRIPTION
       dblink_error_message fetches the most recent remote error message for a given connection.

ARGUMENTS
       connname
           Name of the connection to use.

RETURN VALUE
       Returns last error message, or OK if there has been no error in this connection.

NOTES
       When asynchronous queries are initiated by dblink_send_query, the error message associated
       with the connection might not get updated until the server's response message is consumed.
       This typically means that dblink_is_busy or dblink_get_result should be called prior to
       dblink_error_message, so that any error generated by the asynchronous query will be
       visible.

EXAMPLES
           SELECT dblink_error_message('dtest1');
