Is this 8.2.0? Because the query seems to match the conditions for this
8.2.1 bug fix:
2006-12-07 14:33 tgl
* src/backend/optimizer/plan/: initsplan.c (REL8_2_STABLE),
initsplan.c: Repair incorrect placement of WHERE clauses when there
are multiple, rearrangeable outer joins and the WHERE clause is
non-strict and mentions only nullable-side relations. New bug in
8.2, caused by new logic to allow rearranging outer joins. Per bug
#2807 from Ross Cohen; thanks to Jeff Davis for producing a usable
test case.
