I present the Postgresql server in a Docker container and have performed the necessary mounting operations. I got an error on Postgresql side:
ERROR: database is not accepting commands to avoid wraparound data loss in database "postgres" HINT: Stop the postmaster and vacuum that database in single-user mode.You might also need to commit or roll back old prepared transactions, or drop stale replication slots. CONTEXT: automatic vacuum of table "tablename"
The error is related to postgresql, but I need to stop postmaster in the docker container and log in as a single user. I have no idea how this process works in a Docker container.
