I have a similiar problem with VACUUM FULL ANALYZE.
I do not loose any data, but get hundreds of uninitialized pages and
a segmentation fault. Processing is very slow (twenty minutes).
The only thing unusual about my configuration is that system indices
are bloated. I expect the hardwhere to be ok, but I can not verify it
because the sever is hosted elsewhere.
The last lines of output were:

Running VACUUM FULL ANALYZE another time there were no errors.
