Hi everybody Thank you for your help! I upgrade the version of 9.0.15 to 9.0.17. But after that constantly show this error, in all sessions: *WARNING: terminating connection because of crash of another server process DETAIL: The postmaster has commanded this server process to roll back the current transaction and exit, because another server process exited abnormally and possibly corrupted shared memory. HINT: In a moment you should be able to reconnect to the database and repeat your command. * The problem was in the database template0, this had a problem with the index, I saw in the log when server started, this error: *PANIC: could not open critical system index 2662 * So, I tried REINDEX but this crash. But I saw when I tried connect to the database template0, showed this error: * PANIC: could not open critical system index 2662 * So decided drop database. * DROP DATABASE template0; * But I saw this error: *ERROR: cannot drop a template database * Then run this query and after that DROP DATABASE: *UPDATE pg_database SET datistemplate='false' WHERE datname='template0'; * After that I delete the database template0 and resolved it!!
