大虾进来：pgAdminIII连接虚拟机上POSTGIS

mengjia

env:虚拟机，SCO UNIX 505，POSTGRES 7-3-4
       postgresql.conf:ssl =true
                                 tcpip_socket = true
       pg_hba.conf: host    all         all         10.3.0.204        255.255.255.255   trust
       WIN2000，POSTGRES 8.0-BETA5.
在用pgAdminIII联接虚拟机上的POSTGRES时，报
      server closed the connection unexpectedly
       This probably means the server terminated abnormally before
or while processing the request
在虚拟机上报：FATAL:  unsupported frontend protocol
FATAL:  unsupported frontend protocol
LOG:  server process (pid 857) was terminated by signal 11
LOG:  terminating any other active server processes
WARNING:  Message from PostgreSQL backend:
        The Postmaster has informed me that some other backend
        died abnormally and possibly corrupted shared memory.
        I have rolled back the current transaction and am
        going to terminate your database system connection and exit.
        Please reconnect to the database system and repeat your query.
LOG:  all server processes terminated; reinitializing shared memory and semaphores
