The error isn't due to the number of rows being deleted but rather
from parsing the large number of items in the IN list.  See the
following thread:

http://archives.postgresql.org/pgsql-general/2006-01/msg00959.php

How are you obtaining the N values?  A subquery that returns the
equivalent list should work.  You could also try increasing
max_stack_depth (or max_expr_depth in 7.4 and earlier), but be sure
to stay within your system's stack depth resource limit.
