Solaris should be enough like other Unixen to presume that SIGBUS is 10.
However, that doesn't get you far towards finding a root cause.
Since you have a core file, maybe you could extract a stack trace
from it? We have some suggestions at
https://wiki.postgresql.org/wiki/Getting_a_stack_trace_of_a_running_PostgreSQL_backend_on_Linux/BSD
although I'm afraid that's pretty gdb-specific, and Solaris probably
has different debugging tools.
What PG version are you running, exactly?
