Re: unlogged tables

A very useful feature for unlogged tables would be the ability to
switch them back to normal tables -- this way you could do bulk
loading into an unlogged table and then turn it into a regular table

infrastructure as the above functionality.

Have you thought about switching unlogged tables back to logged? Are
there any significant obstacles?
