Subject: Add PageData C type
X-Git-Tag: REL_18_BETA1~1060
X-Git-Url: http://git.postgresql.org/gitweb/?a=commitdiff_plain;h=6e4df237fbb532e7807cdd97f8b0b0d85093b9ee;p=postgresql.git

Add PageData C type

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 ddbba3aac86, PageData existed
as an unrelated type.)  The type definitions are compatible, so this
doesn't change anything except some of the naming.
