AFAIC, query results are stored as arrays in PGresult structures. Thus, storing huge result sets in a single struct is not very feasible; although, you can face with theoretical limits like MAX_INT in the long run. Moreover, it's so rare to see any practical use of retrieving thousands of rows. If you're getting quite huge sets of data, you should try grouping them with suitable statements. IMHO, you should use cursors to fetch a suitable amount of row from related table and forward it recursively. (Furthermore, I think this is one of the design goals of FETCH mechanism.) Although, as I see from most API implementations (like C++, Perl, PHP, Python and etc.), they use libpq as layer between API and server. Therefore, you'll probably encounter with every limitation of libpq with other programming languages out of C too.
