Oh, wait.  What you need is this patch:

2010-06-06 23:01  itagaki

	* doc/src/sgml/ref/create_table.sgml,
	src/backend/access/common/reloptions.c (REL8_4_STABLE): Ensure
	default-only storage parameters for TOAST relations to be
	initialized with proper values. Affected parameters are fillfactor,
	analyze_threshold, and analyze_scale_factor.
	
	Especially uninitialized fillfactor caused inefficient page usage
	because we built a StdRdOptions struct in which fillfactor is zero
	if any reloption is set for the toast table.
	
	In addition, we disallow toast.autovacuum_analyze_threshold and
	toast.autovacuum_analyze_scale_factor because we didn't actually
	support them; they are always ignored.
	
	Report by Rumko on pgsql-bugs on 12 May 2010.  Analysis by Tom Lane
	and Alvaro Herrera. Patch by me.
	
	Backpatch to 8.4.

which I now realize went in *post* 8.4.4.

We're really overdue for a new set of back-branch releases ...
