如果 Heroku Postgres 不允许 blob，我应该使用什么来存储二进制数据？

2012-05-30T05:59:36+00:00 app[web.1]: [debug] c.j.b.StatementHandle - create table image_info (
2012-05-30T05:59:36+00:00 app[web.1]: id                        bigint not null,
2012-05-30T05:59:36+00:00 app[web.1]: image_id                  varchar(255),
2012-05-30T05:59:36+00:00 app[web.1]: subject_id                varchar(255),
2012-05-30T05:59:36+00:00 app[web.1]: web_thumbnail             blob,
2012-05-30T05:59:36+00:00 app[web.1]: created_date              timestamp,
2012-05-30T05:59:36+00:00 app[web.1]: image                     blob,
2012-05-30T05:59:36+00:00 app[web.1]: thumbnail                 blob,
2012-05-30T05:59:36+00:00 app[web.1]: constraint pk_image_info primary key (id))
2012-05-30T05:59:36+00:00 app[web.1]: [debug] c.j.b.PreparedStatementHandle - update play_evolutions set last_problem = 'ERROR: type "blob" does not exist

使用bytea， blob 不是 PostgreSQL 数据类型。
