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

根据@rkj， @ alannrose， @SharoonThomas， @user3560574提供的答案和@ a_horis_with_no_name的回答

非常感谢。

更好的方法是:更改数据库和模式所有者。

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

如果希望在一条sql语句中完成，则需要定义一个exec()函数，如http://wiki.postgresql.org/wiki/Dynamic_DDL中所述

CREATE FUNCTION exec(text) returns text language plpgsql volatile
  AS $f$
    BEGIN
      EXECUTE $1;
      RETURN $1;
    END;
$f$;

然后你可以执行这个查询，它会改变表，序列和视图的所有者:

SELECT exec('ALTER TABLE ' || quote_ident(s.nspname) || '.' ||
            quote_ident(s.relname) || ' OWNER TO $NEWUSER')
  FROM (SELECT nspname, relname
          FROM pg_class c JOIN pg_namespace n ON (c.relnamespace = n.oid) 
         WHERE nspname NOT LIKE E'pg\\_%' AND 
               nspname <> 'information_schema' AND 
               relkind IN ('r','S','v') ORDER BY relkind = 'S') s;

$NEWUSER是新所有者的postgresql新名称。

在大多数情况下，您需要超级用户才能执行此操作。可以通过将所有者从您自己的用户更改为您所属的角色组来避免这种情况。

感谢RhodiumToad在#postgresql上的帮助。

与@AlexSoto的函数方法相同:

IFS=$'\n'  
for fnc in `psql -qAt -c "SELECT  '\"' || p.proname||'\"' || '(' || pg_catalog.pg_get_function_identity_arguments(p.oid) || ')' FROM pg_catalog.pg_namespace n JOIN pg_catalog.pg_proc p ON p.pronamespace = n.oid WHERE n.nspname = 'public';" YOUR_DB` ; do  psql -c "alter function $fnc owner to NEW_OWNER" YOUR_DB; done

下面这个更简单的shell脚本适合我。

#!/bin/bash
for i in  `psql -U $1  -qt -c  "select tablename from pg_tables where schemaname='$2'"`
do
psql -U $1 -c  "alter table $2.$i set schema $3"
done

其中输入$1 -用户名(数据库) $2 =现有模式 $3 =新模式。

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。

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。
