OSX notes on postgres 9.0 + postgis 1.5.3 -> postgres 9.1.1 + postgis 2.0.0 SVN

gistfile1.txt

The aim here:

1. upgrade postgres
2. then upgrade postgis

For [1], we'll use pg_upgrade to migrate our data.

on OSX, postgres is installed in usr/local using a symlinked pgsql pointing to pgsql-9.0

1. brew install postgresql (9.1.1 = https://github.com/fragility/homebrew/blob/pgsql/Library/Formula/postgresql.rb)
2. brew install postgis (installs 1.5.3 which you will need for migration)
3. remove old usr/local/pgsql -> pgsql-9.0 symlink
4. create new symlink: pgsql -> /usr/local/Cellar/postgresql/9.1.1/
5. ensure postgres is running: launchctl load -w ~/Library/LaunchAgents/org.postgresql.postgres.plist
6. initdb --encoding=UTF8 --locale=en_US (this must match locale of your 9.0 DB for pg_upgrade to work)
7. stop postgres: launchctl unload -w ~/Library/LaunchAgents/org.postgresql.postgres.plist
8. ensure old postgres doesn't have stray postmaster.pids anywhere and all the postgres processes are cleared out
9. you should have a fresh install at /usr/local/pgsql and old install at /usr/local/pgsql-9.0. All servers should be turned off and the new server should be initialised.
10. migrate data: pg_upgrade -d /usr/local/pgsql-9.0/data -D /usr/local/pgsql/data -b /usr/local/pgsql-9.0/bin -B /usr/local/pgsql/bin
11. Check output and fix any errors. Should eventually look like [1]
12. start db (+ verify in htop): launchctl load -w ~/Library/LaunchAgents/org.postgresql.postgres.plist
13. vacuum analyze new database: vacuumdb --all --analyze-only
14. check with your apps. this should be a like for like update to 9.1.1. postgis 2 next up.

| If pg_upgrade fails after this point, you must
| re-initdb the new cluster before continuing.
| You will also need to remove the ".old" suffix
| from /usr/local/pgsql-9.0/data/global/pg_control.old.

Upgrade complete
----------------
| Optimizer statistics are not transferred by pg_upgrade
| so consider running:
| 	vacuumdb --all --analyze-only
| on the newly-upgraded cluster.

| Running this script will delete the old cluster's data files:
| 	/usr/local/Cellar/postgresql/9.1.1/delete_old_cluster.sh

Thanks.
