Hah: There's even a comment about some of the existing dangers:
*
* In PITR replay, the first of these isn't an issue, and the
second
* is only a risk if the CREATE DATABASE and subsequent template
* database change both occur while a base backup is being
taken.
* There doesn't seem to be much we can do about that except
document
* it as a limitation.
*
* Perhaps if we ever implement CREATE DATABASE in a less
cheesy way,
* we can avoid this.
only that it has never been documented as a limitation to my knowledge...
