Probably not if you just copied and pasted into the body of the email.
But if you provided an easy way for someone to replicate your entire
set up (including a driver to emulate the client) someone might look
into that.

The amount of overhead of collecting that amount of timing information
would probably remove whatever the bottleneck used to be by
transferring it to the timing collector.
I bet it is mostly waiting for the connection on the other end to give
it something to do.
If not, pg_stat_statements and autoexplain could be useful.
You could try oprofile to get a more system-wide snapshot.
