I tried to vacuum a database but get the following error. I also tried to
vacuum the individual table tbl_c7links and I get the same error. What is
the problem? The other tables vacuum fine
There are +- 12,000 records in this table

pqReadData() -- backend closed the channel unexpectedly.
This probably means the backend terminated abnormally
before or while processing the request.
