Thread: Where in the source is the "database system identifier" generated?

Can anyone point me to where in the source the database system
identifier is initially generated at? I've looked through initdb.c and I
cannot find it. I've also scoured various other parts of the source to
no avail. I may have more luck if I were an accomplished C programmer,
but alas, I am not.

Any help would be greatly appreciated!

Thanks.

In xlog.c I believe (probably in BootstrapXLog).  But it's not very
interesting, it's just a random number ...
