Hi, I think I was not very clear in my question, what I would like is for the post to be saved completely in the customized table, including ID, post_author, post_date, post_date_gmt, post_content, post_title, post_excerpt, post_status, comment_status, ping_status, post_password, post_name, to_ping, pinged, post_modified, post_modified_gmt, post_content_filtered, post_parent, guid, menu_order, post_type, post_mime_type, comment_count.
In other words, instead of saving the default fields in wp_post save together in wp_custom_table.
