Creating a page does not add a row to pages_parents table

[Toutouwai]

Short description of the issue

I noticed that no new row is added to the pages_parents table when a page is added and published.

In a clean installation of PW 3.0.240...

Page with ID 1019 is added and published:

pages_parents table afterwards (note that there is no row for page ID 1019):

If I add a child page to this newly created page there is no row for that child page either.

I don't understand exactly how the pages_parents table is used, but it looks like it's important for the functioning of the PagesParents class so I wanted to check if it's meant to be added to as pages are created.

Setup/Environment

• ProcessWire version: 3.0.240
