The steps are severely under-documented in pgbench --help output.
Grepping that output I could not find any explanation of these steps,
so I dug through the code and found them in runInitSteps(). Just as I
was thinking of writing a patch to remedy that, just to be sure, I
checked online docs and sure enough, they are well-documented under
pgbench [1].
I think at least a pointer to the the pgbench docs should be mentioned
in the pgbench --help output; an average user may not rush to read the
code to find the explanation, but a hint to where to find more details
about what the letters in --init-steps mean, would save them a lot of
time.
