在PostgreSQL中没有这样的命令。但是您可以使用我之前为GRANTs描述的方法来解决它。

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

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;

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 *.*

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。
