You don't really want the symlink at all.  Just make
/path/to/databases/default a stub file, and update like so:

- create a new database ( /path/to/databases/xapian-index-3 )
- create a new stub-file /path/to/databases/default.tmp containing:
  auto /path/to/databases/xapian-index-3
- atomically update:
  mv /path/to/databases/default.tmp /path/to/databases/default

And for your use:

- check before every request the modtime of /path/to/databases/default
and if newer close / open the database via stub-file

Cheers,
