This script installs PostgreSQL $minversion or later.
If your system runs an older version of PostgreSQL, you must
dump your databases to a file, and then restore them after
installation.
PostgreSQL $minversion is NOT backwards compatible.
If no PostgreSQL databases exist on your system, run the
following command to force the creation of a PostgreSQL $minversion -style
setup:
\tmv $old_pg_home $old_pg_home.old
$restart_instruction
Do not run this command if databases exist that you wish to keep!
