Thomas Munro e37b598028 Add file_extend_method=posix_fallocate,write_zeros. ... Provide a way to disable the use of posix_fallocate() for relation files. It was introduced by commit 4d330a61bb. The new setting file_extend_method=write_zeros can be used as a workaround for problems reported from the field: * BTRFS compression is disabled by the use of posix_fallocate() * XFS could produce spurious ENOSPC errors in some Linux kernel versions, though that problem is reported to have been fixed The default is file_extend_method=posix_fallocate if available, as before. The write_zeros option is similar to PostgreSQL < 16, except that now it's multi-block.
