postgres: upgrade_pg: drop call to analyze_new_cluster.sh

Commit 8f113698b63b15a4e0a4b15d3ee37238c1d1821d upstream:

  Remove analyze_new_cluster script from pg_upgrade

  Since this script just runs vacuumdb anyway, remove the script and
  replace the instructions to run it with instructions to run vacuumdb
  directly.
