It appears all errors are related to the c_acctprocessorlog_pkey index? Run the below to ditch the current index and rebuild with data from the table files.
REINDEX INDEX c_acctprocessorlog_pkey;
It could be a bug in Pg but it's most likely a filesystem corruption or a hardware issue (bad memory, bad disk controller, bad disk itself). You might find some additional useful messages in the kernel logs.
Since you don't mention a version, upgrade to the most recent minor version of Pg very soon.
