In preparation for the addition of Temporary Account data we will need to add a column, is_temp (boolean datatype) to currently active schemas to accommodate this data. (This change only needs to be made on MEP schemas as MP schemas already contain the performer.is_temp column).
| Schema | Column to add | datatype | Status |
| ios_edit_history_compare | is_temp | boolean | TO DO |
| ios_navigation_events | is_temp | boolean | TO DO |
| ios_notification_interaction | is_temp | boolean | TO DO |
| ios_reading_lists | is_temp | boolean | TO DO |
| ios_search | is_temp | boolean | TO DO |
| ios_setting_action | is_temp | boolean | TO DO |
| ios_talk_page_interaction | is_temp | boolean | TO DO |
| ios_watchlists | is_temp | boolean | TO DO |
| ios_edit_interaction | is_temp | boolean | TO DO |
| ios_login_action | is_temp | boolean | TO DO |
| ios_user_history | is_temp | boolean | TO DO |
| editattemptstep | is_temp | boolean | TO DO |
