I am using a Mac with the latest operating system Yosemite.
The upgrade instructions I have found in the archive confuse me in one way:
I would like to upgrade to Postgres.App. In their instructions they say,
"For best results, you should remove any existing installation of PostgreSQL. Here's a run-down of the most common ways you may have installed it previously:"
However, in the instructions on this list, it is recommended (strongly) to use the pg_dump contained in the version you wish to upgrade to to transfer your tables.
I do not understand how I can remove the existing installation with the mission-critical data it contains and use pg_dump from the new version to access that data.
I know I am missing something. Please tell me what.
Thank you very much,
John Gage
