【问题描述】*：
如截图所示，表中字段为varchar类型，insert语句
INSERT INTO "OpenPlatform"."configitem_cfe13440" (_jsonb) VALUES ('{"$s":{"p":{"_id":{"t":"objectId"},"agency":{"t":"object","$s":{"p":{"_id":{"t":"string"},"name":{"t":"string"}},"$k":["_id","name"]}},"itemID":{"t":"string"},"groupID":{"t":"string"},"moduleID":{"t":"string"},"itemField":{"t":"string"},"itemType":{"t":"string"},"itemDescribe":{"t":"string"},"itemValue":{"t":"object","$s":{"p":{"pro":{"t":"string"},"pre":{"t":"string"},"test":{"t":"string"},"dev":{"t":"string"}},"$k":["pro","pre","test","dev"]}},"createTime":{"t":"date"},"createUser":{"t":"object","$s":{"p":{"_id":{"t":"string"},"username":{"t":"string"}},"$k":["_id","username"]}},"updateUser":{"t":"object","$s":{"p":{"_id":{"t":"string"},"username":{"t":"string"}},"$k":["_id","username"]}},"lastUpdateTime":{"t":"date"}},"$k":["_id","agency","itemID","groupID","moduleID","itemField","itemType","itemDescribe","itemValue","createTime","createUser","updateUser","lastUpdateTime"]},"_id":"657bc61d941692ea8fb85e85","agency":{"_id":"","name":"默认机构"},"itemID":"51b81da9-394f-4454-9655-e59ce301b351","groupID":"default_rio_config_group","moduleID":"appmgnt03","itemField":"GlobalPluginConfigTemplate","itemType":"string","itemDescribe":"","itemValue":{"pro":"let buildPlugin = rf.Plugin.buildPlugin(%v, '%v');\n","pre":"","test":"","dev":""},"createTime":1702610461396,"createUser":{"_id":"1d985beb-b975-4abe-923e-8cac2c53a3a2","username":"admin"},"updateUser":{"_id":"1d985beb-b975-4abe-923e-8cac2c53a3a2","username":"admin"},"lastUpdateTime":1702610461396}');

ps：我看varchar最大长度是8188，可能我的数据会大于这个长度，像这种存储json类型的数据，DM建议使用什么方式进行存储
