gistfile1.txt

Steps to install and run PostgreSQL 9.2 using Homebrew (Mac OS X)
(if you aren't using version 9.1.5, change line 6 with the correct version)

1. launchctl unload -w ~/Library/LaunchAgents/homebrew.mxcl.postgresql.plist
2. mv /usr/local/var/postgres /usr/local/var/postgres91
3. brew update
4. brew upgrade postgresql
5. initdb /usr/local/var/postgres -E utf8
6. pg_upgrade -b /usr/local/Cellar/postgresql/9.1.5/bin -B /usr/local/Cellar/postgresql/9.2.0/bin -d /usr/local/var/postgres91 -D /usr/local/var/postgres
7. cp /usr/local/Cellar/postgresql/9.2.0/homebrew.mxcl.postgresql.plist ~/Library/LaunchAgents/
8. pg_ctl -D /usr/local/var/postgres -l /usr/local/var/postgres/server.log start

If you're using ruby, also:

gem pristine pg

Worked 1st time, thanks! 9.5.4 to 9.6.1.

👍 Me too. This is getting repetitive, but the repetitive thanks are well earned.

Worked for 9.5.3 to 9.6.2 - Thanks!

👍

Going from 9.6 to 10.1 on macOS (10.13.1) I had to specify the new local cluster storage for the pg_upgrade call on step 6. To wit:

$ pg_upgrade -b /usr/local/Cellar/postgresql/9.6.3/bin -B /usr/local/Cellar/postgresql/10.1/bin -d /usr/local/var/postgres96 -D /usr/local/var/postgres

Thank you for this. Saved me a lot of time.

Thanks! Worked like charm when I upgrade from 9.6.5 to 10.1.
