To do what exactly?

[FYI for others on the list.]

Currently, a backend is created by forking the postmaster, then exec'ing
an identical binary to run the backend. This change makes it just
fork(), but not exec() a new identical binary.

Why it was originally done this way, I don't know. It was not trivial
to change it. It saves 0.01 seconds on backend startup with single
query, which usually takes 0.08 seconds, so the 0.01 seconds is
significant.

Hey, wow.

Where is it, I am curious. I'll try AIX (will it apply to the last snapshot, I still did not have time
to compile CVSup on my AIX box)
