对于表，你必须循环:

for tbl in `psql -qAt -c "select tablename from pg_tables where schemaname = 'public';" YOUR_DB` ; do  psql -U postgres -c "alter table \"$tbl\" owner to NEW_USER" YOUR_DB ; done

ansible非常简单。你也可以跳过obj_type来修改任何对象类型的所有权。

- name: Reassigner owner of all objects
  postgresql_owner:
    login_user: "{{ postgres_admin_username }}"
    login_unix_socket: "{{postgres_socket}}"
    db: "db-name"
    new_owner: "new-owner"
    reassign_owned_by: "old-owner"
    obj_type: "table"

以下是带有进一步信息的文档:https://docs.ansible.com/ansible/latest/collections/community/general/postgresql_owner_module.html

希望这能有所帮助。

pg_dump as insert statements 
pg_dump -d -O database filename
-d ( data as inserts ) -O ( capital O is no owner )

然后使用以下命令将备份文件输送回PostgreSQL:

psql -d database -U username -h hostname < filename

由于没有包含所有者，因此创建的所有表、模式等都是在指定的登录用户下创建的。

我了解到这也是一个在PostgreSQL版本之间迁移的好方法。

被接受的解决方案不关心函数所有权，下面的解决方案会关心所有的问题(在回顾时，我注意到它类似于上面的@magiconair)

echo "Database: ${DB_NAME}"
echo "Schema: ${SCHEMA}"
echo "User: ${NEW_OWNER}"

pg_dump -s -c -U postgres ${DB_NAME} | egrep "${SCHEMA}\..*OWNER TO"| sed -e "s/OWNER TO.*;$/OWNER TO ${NEW_OWNER};/" | psql -U postgres -d ${DB_NAME}
# do following as last step to allow recovery
psql -U postgres -d postgres -c "ALTER DATABASE ${DB_NAME} OWNER TO ${NEW_OWNER};"

Docker:修改所有表和序列的所有者

export user="your_new_owner"
export dbname="your_db_name"

cat <<EOF | docker run -i --rm --link postgres:postgres postgres sh -c "psql -h \$POSTGRES_PORT_5432_TCP_ADDR -p \$POSTGRES_PORT_5432_TCP_PORT -U postgres -d $dbname" | grep ALTER | docker run -i --rm --link postgres:postgres postgres sh -c "psql -h \$POSTGRES_PORT_5432_TCP_ADDR -p \$POSTGRES_PORT_5432_TCP_PORT -U postgres -d $dbname"
SELECT 'ALTER TABLE '||schemaname||'.'||tablename||' OWNER TO $user;' FROM pg_tables WHERE schemaname = 'public';
SELECT 'ALTER SEQUENCE '||relname||' OWNER TO $user;' FROM pg_class WHERE relkind = 'S';
EOF

对于表，你必须循环:

for tbl in `psql -qAt -c "select tablename from pg_tables where schemaname = 'public';" YOUR_DB` ; do  psql -U postgres -c "alter table \"$tbl\" owner to NEW_USER" YOUR_DB ; done
