To be more precise I used constant number of threads (128 and 1024) to compare
with previous results. The quadratic dependency exists everywhere, see new
graph.

Hi Matthias,
I did additional experiments (changed a number of threads on pgbench side an on
server side) but it did find not chanches.

Sorry, I forgot to add the table and graph for point #8
The graph is attached.
This is the table:
--
| Number of clients | Average init time, ms |
--
| 1024 | ~435 +-20
Hello!
I ran some experiments with pgbench to measure the initialization time and
found that the time increases quadratically with the number of clients. It was
surprising to me and I would like to understand a reason of such behavior.
Some details on how it was done:
1) I used the branch
