Now that you mention it, it tries to do exactly that:

void
quickdie(SIGNAL_ARGS)
{PG_SETMASK(&BlockSig);elog(NOTICE, "Message from PostgreSQL backend:"...

BlockSig includes SIGUSR1.  So why is the quickdie() routine entered
again?  I'm back to suspecting something funny in Solaris' signal
handling...
