Having a root certificate in .postgresql directory is causing Steampipe CLI to fail

[vhadianto]

Describe the bug

Download a valid root certificate. We can use Letsencrypt:

https://letsencrypt.org/certificates/
-> Active -> ISRG Root X1 -> Self-signed
-> Halfway through the page download the certificate (link called "Certificate"). Direct link: https://crt.sh/?d=9314791

Name the certificate root.crt and save it in ~/.postgresql

Now run steampipe, it will fail with the following issue:

$ steampipe query
Welcome to Steampipe v0.13.0-alpha.5

Error: failed to connect to `host=localhost user=root database=postgres`: failed to write startup message (x509: certificate signed by unknown authority)
