Hm, on what filesystem, and what PG version(s)?
I'm not completely satisfied by the its-a-kernel-bug theory, because if
it were then ISTM extending an index would be subject to the same risks
as extending a table; but I see no evidence of index page lossage in
Marc's dump. OTOH the usage patterns are different, so maybe PG isn't
stressing the write-to-lseek path quite as hard for indexes.
