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 --------------------------------------------------------------------- FATAL 1: VACUUM (vc_vacheap): FlushRelationBuffers returned -2 pqReadData() -- backend closed the channel unexpectedly. This probably means the backend terminated abnormally before or while processing the request. connection to server was lost vacuumdb: vacuum failed
