I believe the concern, based on my current understanding of postgres inner workings, is that when a dead tuple is reclaimed by vacuuming: Is that reclaimed space initialized in some fashion that would shred any sensitive data that was formerly there to any inspection by the subsequent owner of that disk page ?

the postgres server owns the pages. AFAIK, the only way to read raw pages is if you can impersonate the server and directly access the raw files, or if you have postgres superuser privileges and use the pg_read_binary_file() functions. no 'normal' client app will be able to see raw pages, or data thats not a valid part of a table that client has permissions to read.
