Manual:Page restrictions table

The page_restrictions table is used to store page levels in MediaWiki 1.10 and later. The most notable feature is the introduction of cascading page protections for high-visibility pages. This table is for restrictions on existing pages only. Protections of non-existent pages are stored in the table.

This table was introduced in MediaWiki 1.10 ( – ), and overrides the field in the  table.

The list of protected pages can be found at Special:ProtectedPages.

pr_id
This is the primary key for the table, and is used to identify a particular row in the table.

pr_page
This field contains a reference to, which works as the foreign key for this table.

pr_type
The type of protection (whether it applies to edits, page moves, or similar) is stored in this field.

pr_level
This column describes the level of protection for the page; full protection for sysop-only pages, semi-protection for autoconfirmed users, or any other levels.

pr_cascade
This field determines whether cascading protection (meaning that all transcluded templates and images on the page will be protected as well).

pr_user
This field is reserved to support a future per-user edit restriction system.

pr_expiry
This field contains the timestamp for pages whose protection has a set expiration date, and has a format similar to the expiry time in the table. Rows that contain a null value in this column are considered to be protected indefinitely.
