我为此创建了一个方便的脚本;pg_change_db_owner.sh。此脚本更改数据库模式中所有表、视图、序列和函数的所有权，以及模式本身的所有者。

请注意，如果你只是想改变一个特定数据库中所有对象的所有权， ，那么您可以简单地使用REASSIGN owned命令来代替。

可以使用REASSIGN OWNED命令。

剧情简介:

重新分配old_role[，…]到new_role

这将把old_role拥有的所有对象更改为新角色。你不需要考虑用户拥有什么样的对象，它们都会被改变。注意，它只应用于单个数据库中的对象。它也不会改变数据库本身的所有者。

它至少可以在8.2版本中使用。他们的网上资料只能追溯到这段时间。

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。

我不得不改变表，视图和序列的所有权，并发现@rjk发布的伟大解决方案工作得很好-尽管有一个细节: 如果对象名称是大小写混合的(例如。"TableName")，这将失败，并报错"not found"。 为了避免这种情况，可以像这样用' " '来包装对象名称:

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;

参见REASSIGN OWNED命令

注意:正如@trygvis在下面的回答中提到的，REASSIGN OWNED命令至少在8.2版本中就可用了，而且是一个更简单的方法。

因为要更改所有表的所有权，所以可能还需要视图和序列。以下是我所做的:

表:

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

序列:

for tbl in `psql -qAt -c "select sequence_name from information_schema.sequences where sequence_schema = 'public';" YOUR_DB` ; do  psql -c "alter sequence \"$tbl\" owner to NEW_OWNER" YOUR_DB ; done

视图:

for tbl in `psql -qAt -c "select table_name from information_schema.views where table_schema = 'public';" YOUR_DB` ; do  psql -c "alter view \"$tbl\" owner to NEW_OWNER" YOUR_DB ; done

您可能会DRY它一点，因为alter语句对所有三个都是相同的。

我喜欢这个，因为它可以一次性(在一个sql语句中)修改某个模式的表、视图、序列和函数所有者，而不需要创建函数，你可以直接在PgAdmin III和psql中使用它:

(在PostgreSql v9.2中测试)

DO $$DECLARE r record;
DECLARE
    v_schema varchar := 'public';
    v_new_owner varchar := '<NEW_OWNER>';
BEGIN
    FOR r IN 
        select 'ALTER TABLE "' || table_schema || '"."' || table_name || '" OWNER TO ' || v_new_owner || ';' as a from information_schema.tables where table_schema = v_schema
        union all
        select 'ALTER TABLE "' || sequence_schema || '"."' || sequence_name || '" OWNER TO ' || v_new_owner || ';' as a from information_schema.sequences where sequence_schema = v_schema
        union all
        select 'ALTER TABLE "' || table_schema || '"."' || table_name || '" OWNER TO ' || v_new_owner || ';' as a from information_schema.views where table_schema = v_schema
        union all
        select 'ALTER FUNCTION "'||nsp.nspname||'"."'||p.proname||'"('||pg_get_function_identity_arguments(p.oid)||') OWNER TO ' || v_new_owner || ';' as a from pg_proc p join pg_namespace nsp ON p.pronamespace = nsp.oid where nsp.nspname = v_schema
    LOOP
        EXECUTE r.a;
    END LOOP;
END$$;

非常感谢。

更好的方法是:更改数据库和模式所有者。

        select 'ALTER TABLE "' || sequence_schema || '"."' || sequence_name || '" OWNER TO ' || v_new_owner || ';' as a from information_schema.sequences where sequence_schema = v_schema
