[dependabot-preview]

Bumps pg from 7.1.0 to 7.12.1. This update includes a security fix.

Vulnerabilities fixed

Sourced from The GitHub Security Advisory Database.

High severity vulnerability that affects pg
A remote code execution vulnerability was found within the pg module when the remote database or query specifies a specially crafted column name. There are 2 likely scenarios in which one would likely be vulnerable. 1) Executing unsafe, user-supplied sql which contains a malicious column name. 2) Connecting to an untrusted database and executing a query which returns results where any of the column names are malicious.

Affected versions: >= 7.1.0 < 7.1.2
