I have installed Postgresql 8.4 and just started with it when I decided I wanted to upgrade it to Postgresql 9.1.1.
I researched upgrade and choose the pg_upgrade option since I did not have a complex database at this point.
When I type pg_upgrade in my console, Ubuntu 10.04, I get pg_upgrade: command not found.
It turns out that pg: Usage: is pg [-number] etc but no pg_upgrade.
Any suggestions on how to go about upgrading Postgresql 8.4 to 9.1.1, that is short of uninstall 8.4 and re-installing 9.1 .... thanks.
