In commit 33e05f89c5, we have added the option to display WAL usage statistics in Explain and auto_explain. The display format used two spaces between each field which is inconsistent with Buffer usage statistics which is using one space between each field. Change the format to make WAL usage statistics consistent with Buffer usage statistics. This commit also changed the usage of "full page writes" to "full page images" for WAL usage statistics to make it consistent with other parts of code and docs.
