    Reword activity message to avoid truncation
    
    The message sent to pg_stat_activity when waiting for transactions to
    end was long enough that it could get truncated when the xid included
    in the string grew large. Fix by rewording to avoid truncation, using
    a similar message in the logical replication code as inspiration.
