The problem with posix_fallocate (other than questionable portability) is that it doesn't appear to guarantee anything at all about what is in the space it allocates. Worst case, we might find valid-looking Postgres data there (eg, because a block was recycled from some recently dropped table). If we have to write something anyway to zero the space, what's the point? regards, tom lane -- Sent via pgsql-performance mailing list (pgsql-performance@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-performance
