HI Gurus
I'm seeing a issue with some temp tables in contrib_regression db , the
auto vacuum job will not run for this tables due some files/QID's
missing how can I fix this ?
The temp tables are growing too fast and they don't get
empty/clean-up...any tips ? I 'm running PGSQL 8.3.6 on RHES.
Isabella

Um ... in general, autovacuum just silently ignores temp tables, because
it doesn't have any way to access their contents. (One of the reasons
that temp tables are fast is that the backend owning a temp table keeps
its data in local buffers, not in shared buffers that another process
could access.) I wouldn't expect any "missing file" complaints though.
What exactly were you seeing?
regards, tom lane

Hi Tom ,
Here is my error , the missing files were removed by mistake , I have
another similar db cfg with this tables:spherrtmp% and no issues.
I 'm thinking to restore this tables content from this second db ,
will this eliminate the auto vacuum error ?

What you ought to do is drop the tables that are reported as causing the
error. Or the whole database --- are you actually doing something
useful in contrib_regression, or is that just left over from testing?
