Well, we use 'usecs' all over our code, and in pg_test_timing:
Histogram of timing durations:
< usec % of total count
1 95.86499 69510498
2 4.13395 2997478
4 0.00062 453
8 0.00042 301
16 0.00001 8
32 0.00000 1
Microseconds just isn't going to fit there. Postgres understands usec:
test=> select '1 usec'::interval;
interval
-----------------
00:00:00.000001
(1 row)
I think the people running these tools are going to know usec.
