Hypothesis: the pages of the TOAST table on the slave have more unused space in them than the pages of the TOAST table on the master. How do I test this hypothesis? I need to examine the raw pages on disk. I'm looking at http://momjian.us/main/writings/pgsql/internalpics.pdf Slide 52 shows "internal page structure" but I don't know how to actually look at a page. Is it possible to do a raw dump of the pages of a table? Do I just look at the hexdump of the file corresponding to relfilenode?
