Due to interest I tried to look it up in the manual and did not found
such a number, until it occured to me, that regarding the underlying
structure of the database files, there is probably no row limit, but
only a file size limit (by data pointer size). 

So the number of rows would be MAXSIZE / average_row_length and that
is quite a lot (as the newer versions support 64Bit pointers).
