Re: pg_attribute always grow...

Will the same occur if I create real tables instead of temporary tables as
for most of them, there is no concurrent access and no need to have the same
table in two different connexions...
What's the real performance difference between a temporary table and other
tables...

Thanks

Yes, it could very well be that.  I am quite embarassed by our need to
reindex.
