# What to do When Your Package System Maintainer Fails You

The other day I upgraded the Homebrew package for PostgreSQL 15.5. I found my self without the expected command line programs, specifically the one I use most: `psql`

. After a brief moment of panic of what I did wrong, I discovered from poking around the Homebrew PR that updated the package that someone decided everyone only ever used “older” versions of Postgres by updating their path instead of using the `brew link`

option. The new right way was to use version-specific commands like `psql-15`

which is epically stupid.

The quickest fix I could think of was to revert to the prior package. It turns out that there is documentation how to do this, but it is scattered about. Here I summarize how I got Homebrew to reinstall the Postgres 15.5_1 package, which uses sane command names.

First, download the 15.5_1 version of the formula. The “right” way to do this is supposed to be to run `brew extract --version=15.5_1 postgresql@15 $USER/taps`

but it complains: `No available formula with the name "homebrew/core/postgresql@15"`

.

The remaining steps are just following how to create your own tap into Homebrew then installing the package from there:

```
brew tap-new $USER/taps
mv ~/Downloads/postgresql@15.rb /opt/homebrew/Library/Taps/$USER/homebrew-taps/Formula
brew install $USER/taps/postgresql@15
brew link postgresql@15
```

There were sufficient complaints on the PR and issue I opened that this change was reverted. Still, this fix saved me for a day or two.
