@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

根据elysch的回答，这里有一个针对多个模式的解决方案:

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

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

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。

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

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。
