WARNING: database "dbname" must be vacuumed within 5463629 transactions
HINT: To avoid a database shutdown, execute a database-wide VACUUM in that database.
You might also need to commit or roll back old prepared transactions. VACUUM
I have run
vacuumdb --full -h 127.0.0.1 -U postgres dbname
It spits out that message galore.
I have checked active queries and there is nothing active.
It is a cluster with many DBs on Linux (postgres 9.5.10) but only this one small DB is giving this warning.
Any suggestion would be helpful.
