pspg doesn't support this feature. Theoretically it can be implementable (I
am able to hold two datasets now), but without any help with
synchronization I don't want to implement any more complex parsing. On the
pspg side I am not able to detect what is the first result in the batch,
what is the last result (without some hard heuristics - probably I can read
some information from timestamps). And if you need two or more results in
one terminal, then mode without pager is better.
