Again, I'm kinda shooting in the dark here as you reveal more and more
what you are doing a little at a time. A test case that can invoke
this failure would be most useful.
After seeing this today:

...there was little or no activity during this time, apart from
some inserts, maybe some selects, etc. Nothing that should
have caused this kind of upset.
There is a file that matches this:
-rw------- 1 postgres wheel 57344 Oct 14 22:57
/data/db/second/base/10793/2659
but it isn't in the directory where I moved most of the indexes to:
ls /data/index/ext/10793/
16390 16397 16399 16406 16407 16410 16414 16425 16434 16435
I don't know if the file numbers have any meaning?
But in addition, the list of tables (\dp) is now fubar'd.
I'm starting to wonder if it is a combination of:
- the operating system (NetBSD 4.99.20)
- the hardware (small HP box, not meant for hard work like this but
shouldn't be impossible for it)
- the way pkgsrc compiles postgresql for NetBSD
I'm shying away from the hardware (or at least RAM/CPU) because I'd
expect there to be some other kind kinds of faults show up, ultimately
leading to a panic due to just random corruption of some kernel data
structure. As it is, everything else seems to be functioning ok.
