Hmph. You should carry the "du" analysis down to the subdirectory
level, eg make sure that it's not a case of lots of pg_xlog bloat
balancing out bloat in a different area on the other system. But I
suspect you won't find anything.

I tend to agree. You might try watching "vmstat 1" output while taking
the dumps, so you could at least get a clue whether the problem is CPU
or I/O related ...
