Upgrade PostgreSQL 9.5.5 to 9.6.4 using Homebrew (macOS)
View gist:a0ae3c0bd2ad143f935f5a2421ec0f9f
After automatically updating Postgres to 9.6.1 via Homebrew, the pg_ctl start command didn't work.
The error was something like "database files are incompatible with server".
Database files have to be updated before starting the server, here are the steps that had to be followed:
# need to have both 9.6.x and latest 9.5.x installed, and keep 9.6.4 as default
brew services stop postgresql
brew unlink postgresql
brew install postgresql95
brew unlink postgresql95

# There will be 2n moves (or 20 in this case). However we only care about one directional unit (down or right).
# So if you think about 2n moves numbered 1 though 2n (or 1 - 20)
# The number of possible paths can be represented by the number of combinations of
# n of those numbers. So for 20 numbers, how many combinations of 10 of those numbers can you make.
