This is implemented using anonymous virtual memory; extensions on the same
address are guaranteed because a large non-committed VM area is requested

/* Convert the old-style string heap to the new style.
This function must be called at the end of BBPinit(), just before
"normal processing" starts. All errors that happen during the
- conversion are fatal. This function is "save" in the sense that
+ conversion are fatal. This function is "safe" in the sense that
when it is interrupted, recovery will just start over. No
permanent changes are made to the database until all string heaps
have been converted, and then the changes are made atomically.
