+# Search For Homebrew Packages To Install
+
+Let's say we want to install the latest version of PostgreSQL with `brew`, but
+we aren't sure either what formulas are available nor what the exact name would
+be.
+
+We can run a search with the `brew search` subcommand to get an idea of what is
+available.
+
+If I run this for even the shorthand of `postgres`, I get a useful set of
+results showing me what versions I already have installed and what else is
+available.
+
+```bash
+$ brew search postgres
+==> Formulae
+check_postgres    postgresql@11 ✔   postgresql@13     postgresql@15     postgrest         postgis
+postgresql@10     postgresql@12     postgresql@14     postgresql@16     qt-postgresql
+
+==> Casks
+navicat-for-postgresql               postgres-unofficial                  sqlpro-for-postgres
+postbird                             postgrespreferencepane
+
+If you meant "postgres" specifically:
+postgresql breaks existing databases on upgrade without human intervention.
+
+See a more specific version to install with:
+  brew formulae | grep postgresql@
+```
+
+I can then go on to run `brew install postgresql@16` to get the latest.
+
+See `brew search --help` for more details.
