Do not connect Volume Pg?

Question

PostgreSQL

Good afternoon, you can tell me about the docker. I
can’t connect the Volume to the container folder so that the database files become available and backups can be made .

postgresql_1 | run server:
postgresql_1 | postgres: could not access directory "/var/lib/pgsql/data": No such file or directory
postgresql_1 | Run initdb or pg_basebackup to initialize a PostgreSQL data directory.
postgresql_1 | Creating user "golang"...
postgresql_1 | postgres: could not access directory "/var/lib/pgsql/data": No such file or directory
postgresql_1 | Run initdb or pg_basebackup to initialize a PostgreSQL data directory.
postgresql_1 | Creating database "smpp"...
postgresql_1 | postgres: could not access directory "/var/lib/pgsql/data": No such file or directory
postgresql_1 | Run initdb or pg_basebackup to initialize a PostgreSQL data directory.
postgresql_1 | Granting access to database "smpp" for user "golang"...
postgresql_1 | postgres: could not access directory "/var/lib/pgsql/data": No such file or directory
postgresql_1 | Run initdb or pg_basebackup to initialize a PostgreSQL data directory.
postgresql_1 | configure postgresql.conf:
postgresql_1 | sed: can't read /var/lib/pgsql/data/postgresql.conf: No such file or directory
postgresql_1 | run server:
postgresql_1 | postgres: could not access directory "/var/lib/pgsql/data": No such file or directory
postgresql_1 | Run initdb or pg_basebackup to initialize a PostgreSQL data directory.
