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?
