To successfully update Memoria database there should be no requests from Cerebro clients to the database in the process.

You can solve this by using PostgreSQL tools, limiting the range of network addresses that are allowed to connect to the database. To do this, do the following operations.

Host   all   all   127.0.0.1/32  ident
#Host   all   all   0.0.0.0/0    md5

Warning

When Memoria database is finished updating, do not forget to rollback PostgreSQL access permissions, for this you should uncomment commented out lines in pg_hba.conf and restart the service.
