Java, do you trust me? 🤔

Using openssl to test an SSL connection to google.com, using a CA file that's been pulled out from a Java keystore. For those days when you want to verify that you've got the right certificate in the store:

1. Download the Equifax root certificate (which is the root CA for Google)
2. Import the certificate into a new Java keystore
3. Export the certificate back out again
4. Convert the certificate to PEM
5. Use openssl to test an SSL connection to Google with that cert

PSQL

Magic words:

psql -U postgres

If run with -E flag, it will describe the underlaying queries of the \ commands (cool for learning!).

Most \d commands support additional param of __schema__.name__ and accept wildcards like *.*
