I raised the question on the Debian developers' list. As far as I can see, the general feeling is that it won't break anything but will only work with kernel 2.4. It may break with 2.0, but 2.0 is no longer provided with Debian stable, so I don't mind that. The thread starts at http://lists.debian.org/debian-devel/2002/debian-devel-200208/msg00597.html I intend to enable it in the next version of the Debian packages (which will go into the unstable archive if this works for me) by adding -D_GNU_SOURCE -D_FILE_OFFSET_BITS=64 to CFLAGS for the entire build. One person said: However compiling with largefile support will change the size of off_t from 32 bits to 64 bits - if postgres uses off_t or anything else related to file offsets in a binary struct in one of the database files you will break stuff pretty heavily. I would not compile postgres with largefile support until it is officially supported by the postgres developers. but I cannot see that off_t is used in such a way. -- Oliver Elphick [EMAIL PROTECTED] Isle of Wight, UK http://www.lfix.co.uk/oliver GPG: 1024D/3E1D0C1C: CA12 09E0 E8D5 8870 5839 932A 614D 4C34 3E1D 0C1C ======================================== "And he spake a parable unto them to this end, that men ought always to pray, and not to faint."
