PQntuples returns an int.

Hello.

I've been looking at the PQntuples function, in section 29.3.2.
'Retrieving query result information' of

    http://www.postgresql.org/docs/8.2/interactive/libpq-exec.html

The declaration is:

> int PQntuples(const PGresult *res);

I'm wondering: why the 'int'? why not a 'long int', or an 'unsigned
int', or whatever?

I'm asking this because I'm wondering whether you could have more tuples
in the result of a query than could be indexed by the 'int' type. May
this happen?

All the best,
