Add PageData C type

petere · petere · commit 6e4df237fbb5 · 2025-01-20T11:06:49.000+01:00
This adds the C type PageData and makes the existing type Page a pointer to it. This follows the usual PostgreSQL C type naming scheme of Foo/FooData pairs. (Prior to commit ddbba3a, PageData existed as an unrelated type.) The type definitions are compatible, so this doesn't change anything except some of the naming.
