org.postgresql.util.PSQLException: Error could not open file "base/":No such file or directory

Hi,

Few of the tables and indexes are bloated though auto vacuum has enables.

Two reclaim the space vacuum, I have ran vacuum full on the larger tables and also performed reindex on the indexes which are in larger size. Now the size of the database is in control.

After perfoming the vacuum full and reindexing on larger tables, I am facing below error.

Please guide me how to resolve the above error and let me know does this has any relation with vacumm full or reindexing operation which are performed by me.
