Display post metas on pages

Hello,

I’m trying to add post metas on pages, to display in particulary the publication or update date of the page, just after the title like on posts.

I allready tried to add a part of the code of post_heading and regular_post_heading templates on page_heading and regular_page_heading templates, but it did’nt work.

Is someone have a hint or, better, a solution to this problem ?

Thank you !

Céline
