Hopefully we won't gain too many callers of this function, and ...

... it is almost impossible to tell from the call site which one is
for initializing the ODB (hint: "true" does initialize the ODB, oh,
no it is the other way around, or is it correct?  now everybody is
confused).

We could do "enum { INIT_DB, NO_INIT_DB }" instead of bool and the
calling sites would become self-describing, but as long as we won't
have too many calling sites, the current code should be OK.
