Here is the updated version (v8? I'm not sure what the right count is), which works for me and for "make check", including some tests added for uncovered paths.
I included your tap test (thanks again!) with some more comments and cleanup.
I tested manually for the pager feature, which mostly work, althoug "pspg --stream" does not seem to expect two tables, or maybe there is a way to switch between these that I have not found.
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.
