Run a PostgreSQL .sql file using command line arguments

How to Run a PostgreSQL .sql File using Command Line Arguments 💻

Are you struggling to run those massive .sql files with thousands of INSERT statements in your PostgreSQL database? Don't fret, we've got you covered! In this guide, we'll address the common issue of running these inserts via the command line, provide easy solutions, and ensure you can add those statements to your table hassle-free. Let's dig in! 😎

The Command Line Magic ✨

To execute those INSERT statements using the command line, you'll need to navigate to the bin folder within your PostgreSQL installation (this is where the "psql" executable resides). 🗂️

1. Open your favorite terminal and move to the PostgreSQL bin folder.

   cd /path/to/postgres/bin

2. Now, you're ready to unleash the power of command line arguments. Execute the following command, but ensure to replace myDataBase with the name of your database and myInsertFile with the path to your .sql file:

   psql -d myDataBase -a -f myInsertFile

3. Let's make this more relatable with an example. If your database is named "HIGHWAYS" and the .sql file you want to execute is called "CLUSTER_1000M.sql", the command will look like this:

   psql -d HIGHWAYS -a -f CLUSTER_1000M.sql

The Password Predicament 🔒

Ah, the dreaded password authentication error. 😫 The command line demands a password, but when you try to enter it, it seems to ignore you, leaving you puzzled and frustrated. Fear not, for we have a workaround to help you out! 💪

1. Open the pg_hba.conf file, which can usually be found in the 'data' folder of your PostgreSQL installation.

2. Add a new entry in the following format:

   # IPv6 local connections: host myDbName myUserName ::1/128 trust

   Replace myDbName with the name of your database and myUserName with your username.

3. Save the changes to the pg_hba.conf file.

And voila! 💥 With these modifications, running your .sql file using the command line should no longer ask for a password and instead proceed smoothly. You can now execute those INSERT statements without any hindrance. 🚀
