Storage test was simple, but the data (seconds taken) for INSERT test for PG vs 
Oracle for 1, 2, 3,4 and 5 indexes was:
PG:

25 
30 
37 
42 
45 

Oracle:


33 
43 
50 
65 
68 Rows inserted: 100,000 
Above results show good INSERT performance of PG when using SQL procedures. But 
performance when I use C++ lib is very bad. I did that test some time back so I 
do not have data for that right now.

Tell us more about your tests and results please.
