Docker:修改所有表和序列的所有者

export dbname="your_db_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。

您可以在PostgreSQL 9中尝试以下操作

DO $$DECLARE r record;
BEGIN
    FOR r IN SELECT tablename FROM pg_tables WHERE schemaname = 'public'
    LOOP
        EXECUTE 'alter table '|| r.tablename ||' owner to newowner;';
    END LOOP;
END$$;

@Alex Soto的答案是正确的，@Yoav Aner上传的要点也有效，前提是在表/视图名称中没有特殊字符(在postgres中是合法的)。

你需要转义它们来工作，我已经上传了一个要点:https://gist.github.com/2911117

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

从其他人的讨论来看，他们不同意我的问题。如前所述，如果所有者是postgres, REASSIGN OWNED不工作。所以，受之前讨论的启发，我写了这个脚本:

CREATE OR REPLACE FUNCTION public.alt_own_onall (v_new_owner text)

    v_new_owner := quote_ident (v_new_owner);
    IF v_new_owner NOT IN
        (SELECT role_name FROM information_schema.enabled_roles WHERE role_name <>'postgres')
        THEN
            RAISE WARNING '[%] est inconnu', v_new_owner;

;$alt_own_onall$;

在PSQL下使用它: SELECT alt_own_onall ('new_role_name'); 你必须把法语信息翻译成你自己的语言。 适用于pg 9.5
