+# PostgreSQL
+
+Install local PostgreSQL database for your projects and PoCs.  
+We will be using [TimescaleDB](https://www.timescale.com/) as **PostgreSQL** which add extentions `pgvectorscale` and `pgai` to support [AI](https://www.timescale.com/ai)
+
+## Setup
+
+1. At the command prompt, add the TimescaleDB Homebrew tap:
+
+```shell
+brew tap timescale/tap
+```
+
+2. Install TimescaleDB and psql:
+
+```shell
+Install TimescaleDB and psql:
+```
+
+3. Update your path to include psql.
+
+```shell
+brew link --force libpq
+```
+
+4. Run the timescaledb-tune script to configure your database:
+
+```shell
+timescaledb-tune --quiet --yes
+```
+
+5. Change to the directory where the setup script is located. It is typically, located at
+
+`/opt/homebrew/Cellar/timescaledb/<VERSION>/bin/`, where `<VERSION>`is the version of `timescaledb` that you installed:
+
+```shell
+cd /opt/homebrew/Cellar/timescaledb/<VERSION>/bin/
+```
+
+6. Run the setup script to complete installation.
+
+```shell
+./timescaledb_move.sh
+```
+
+7. Login to PostgreSQL as postgres
+
+```shell
+sudo -u postgres psql
+```
+
+8. Set the password for postgres (optional)
+
+```shell
+\password postgres
+```
+
+When you have set the password, type `\q` to exit psql.
