# We need to create quite large index (more than one gigabyte segment) to reproduce write error caused by this race condition
# (backend completed unlogged build removes local files while backend evicting page tries to write to the file).
# If index size is smaller than segment size, the problem is avoided by file descriptor cache which prevents file deletion.
