I don't think you'll run into too many issues if your needs are simple. 
The only thing that I can think of that you might run into is:

7.3    tuplestore_begin_heap(true, SortMem)
7.4    tuplestore_begin_heap(true, false, SortMem)

And that will only apply if you have an SRF that returns a tuplestore 
(contrib/tablefunc as an example). You can continue to use elog in 7.4 
-- you just don't get to take advantage of the better ereport functionality.

HTH,
