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:
Oracle:
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.
