Re: [GENERAL] database is not accepting commands

We have 1.5 TB database that's shown an error and block all commands.
The error is :
"ERROR:  database is not accepting commands to avoid wraparound data loss in
database "dbname"
HINT:  Stop the postmaster and use a standalone backend to vacuum that
database.
You might also need to commit or roll back old prepared transactions."

I tried to do vacuum in the backend mode. Also I tried to set
zero_damaged_pages = on then do the vacuum again but same error appeared.
The error appeared after two hours of vacuuming where verbose shows passing
tables.

Postgres version?

So was all the above done in the standalone backend?

The cause of error could be :
1- a lot of insertion queries for not existing table
or
2- truncating data with 40 GB in a week,
we used to do that but this is the first time we had this error.
also, autovacuume is turned on.

Please , I need help or any suggestion?
