That's really odd. The only theory that comes to mind is that there's
something different about the execution environment under cron, but it's
pretty hard to see how that would allow pg_dumpall to get as far as the
log shows and then crash. For instance, if you had a LD_LIBRARY_PATH
setting in your manual environment that wasn't shared by cron, that
could lead to pg_dumpall picking up the wrong copy of libpq.so and then
crashing --- but you'd really expect such a failure to happen at or near
the start of execution.

What I'd try next is (1) adding an "env" command to the cron shell
script so you can compare that environment to your regular shell,
and (2) adding "ulimit -c unlimited" to the shell script in hopes
of collecting a core dump you could get a stack trace from.
