That is not exactly true, look at Section 3.6.8 of the mathematica book.
Type 3.6.8 in the Mathematica Book Tab of the help browser at the end 
there is
In[14]:=
RSolve[a[i + 1, j + 1] == i j a[i, j], a[i, j], {i, j}]

Out[14]=
\!\({{a[i, j] \[Rule] \(Gamma[i]\ Gamma[j]\ \(C[1]\)[i - j]\)\/Gamma[1 - 
i + \
j]}}\)
