I would intuit that it's fine, but I just want to make sure there are
no gotchas from a recovery point of view:

If I were to lose my temp tablespace upon system crash, would this
prevent proper crash recovery?

Also, if I were to omit the temp tablespace from the base backup,
would that prevent proper backup recovery?


Although it would be nice if what you said would work, I read in a recent
blog post that losing any tablespace would prevent the database server from
starting, even if it was only for temporary things. -- Darren Duncan

That is unfortunate.  Good thing I asked, I guess.  Do you have a
pointer to said blog post?

I think this is the post in question:

Yes, that looks like it. -- Darren Duncan
