This is a known bug --- the postmaster's routine for catching ECHILD
signals needs to save and restore errno.  We have not made a patch for
7.0.*, but you could probably adapt the patch that was applied to
current sources:

http://www.postgresql.org/cgi/cvsweb.cgi/pgsql/src/backend/postmaster/postmaster.c.diff?r1=1.198&r2=1.199&f=c

The changes in reaper() are probably the only critical part.
