WAL logging of SELECT ... INTO command

Currently, it appears that SELECT * INTO new_table FROM old_table logs
each page as it's written to WAL. Is this actually needed? Couldn't the
database simply log that the SELECT ... INTO statement was executed
instead? Doing so would likely result in a large performance improvement
in most installs. Is there no provision for writing anything but data
page changes (or whole pages) to WAL?
