很简单，试试看…

 select 'ALTER TABLE ' || table_name || ' OWNER TO myuser;' from information_schema.tables where table_schema = 'public';

从PostgreSQL 9.0开始，你可以GRANT [priv名称]ON ALL[对象类型]in SCHEMA，其中[priv名称]是典型的SELECT, INSERT, UPDATE, DELETE等，[对象类型]可以是其中之一:

表 序列 功能

PostgreSQL的GRANT和REVOKE文档对此有更详细的说明。在某些情况下，仍然需要使用涉及系统编目(pg_catalog.pg_*)的技巧，但这种情况并不常见。我经常做以下事情:

开始一个事务来修改privs 将数据库的所有权更改为“DBA角色” 将schema的所有权更改为“DBA角色” 撤销所有角色的所有表、序列和函数上的所有私权 将相关/适当表上的SELECT、INSERT、UPDATE、DELETE权限授予适当的角色 提交DCL事务。

根据elysch的回答，这里有一个针对多个模式的解决方案:

DO $$
DECLARE 
  r record;
  i int;
  v_schema text[] := '{public,schema1,schema2,schema3}';
  v_new_owner varchar := 'my_new_owner';
BEGIN
    FOR r IN 
        select 'ALTER TABLE "' || table_schema || '"."' || table_name || '" OWNER TO ' || v_new_owner || ';' as a from information_schema.tables where table_schema = ANY (v_schema)
        union all
        select 'ALTER TABLE "' || sequence_schema || '"."' || sequence_name || '" OWNER TO ' || v_new_owner || ';' as a from information_schema.sequences where sequence_schema = ANY (v_schema)
        union all
        select 'ALTER TABLE "' || table_schema || '"."' || table_name || '" OWNER TO ' || v_new_owner || ';' as a from information_schema.views where table_schema = ANY (v_schema)
        union all
        select 'ALTER FUNCTION "'||nsp.nspname||'"."'||p.proname||'"('||pg_get_function_identity_arguments(p.oid)||') OWNER TO ' || v_new_owner || ';' as a from pg_proc p join pg_namespace nsp ON p.pronamespace = nsp.oid where nsp.nspname = ANY (v_schema)
        union all
        select 'ALTER DATABASE "' || current_database() || '" OWNER TO ' || v_new_owner 
    LOOP
        EXECUTE r.a;
    END LOOP;
    FOR i IN array_lower(v_schema,1) .. array_upper(v_schema,1)
    LOOP
        EXECUTE 'ALTER SCHEMA "' || v_schema[i] || '" OWNER TO ' || v_new_owner ;
    END LOOP;
END
$$;

非常简单

Su - postgres psql 重新分配[old_user]到[new_user]; \c[你的资料库] 重新分配[old_user]到[new_user];

完成了。

http://archives.postgresql.org/pgsql-bugs/2007-10/msg00234.php也是一个很好的快速解决方案，适用于一个数据库中的多个模式:

表

SELECT 'ALTER TABLE '|| schemaname || '."' || tablename ||'" OWNER TO my_new_owner;'
FROM pg_tables WHERE NOT schemaname IN ('pg_catalog', 'information_schema')
ORDER BY schemaname, tablename;

序列

SELECT 'ALTER SEQUENCE '|| sequence_schema || '."' || sequence_name ||'" OWNER TO my_new_owner;'
FROM information_schema.sequences WHERE NOT sequence_schema IN ('pg_catalog', 'information_schema')
ORDER BY sequence_schema, sequence_name;

的观点

SELECT 'ALTER VIEW '|| table_schema || '."' || table_name ||'" OWNER TO my_new_owner;'
FROM information_schema.views WHERE NOT table_schema IN ('pg_catalog', 'information_schema')
ORDER BY table_schema, table_name;

物化视图

基于这个答案

SELECT 'ALTER TABLE '|| oid::regclass::text ||' OWNER TO my_new_owner;'
FROM pg_class WHERE relkind = 'm'
ORDER BY oid;

这将生成所有必需的ALTER TABLE / ALTER SEQUENCE / ALTER VIEW语句，复制这些语句并将它们粘贴回plsql以运行它们。

检查你在psql中的工作，执行以下操作:

\dt *.*
\ds *.*
\dv *.*

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
