The script already deletes the 8.4 database directories, but leaves
PG_VERSION behind. Why keep it when all the 8.4 data is gone? The
script also dates PGDATA for 8.4, so there is nothing left pointing to
that directory. Here are the delete script file contents after the
patch:
#!/bin/shrm -rf /u/pgsql.old/datarm -f /rtmp/pgsql/PG_VERSIONrm -rf /rtmp/pgsql/1rm -rf /rtmp/pgsql/11564rm -rf
/rtmp/pgsql/16384rm-rf /rtmp/pgsql/16385rm -rf /rtmp/pgsql/27628
