The idea was to have postgresql, internally, totally ignore symlinks - use
OID or whatever is technically best for file names. Then create a
utility/command to make human-centric symlinks in a known location. The
symlinks *could* be updated automatically by postgres, if possible, but
would never be used internally. Things like vacuum could report out of date
symlinks, and maybe fix them (but probably not).
It may sound crude, but the only reason for the symlinks is for humans to
'see what is going on', and in most cases they wont be very volatile.
