Try ANALYZING both right before running the check, to get the best row and
pages estimates. At the very least, the number of rows should match much
closer than they are. It may just be that the vacuum on the slave side did
not run as recently as the master, or could not completely remove all dead
tuples. Compare ANALYZE VERBOSE on both sides for a closer look at the
differences.
