[Security] Bump pg from 4.1.1 to 4.5.7

[dependabot-preview]

Bumps pg from 4.1.1 to 4.5.7. 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: >= 4.0.0 < 4.5.7

Changelog

All major and minor releases are briefly explained below.

• Support passing a string of command line options flags via the { options: string } field on client/pool config.

• Switch internal protocol parser & serializer to pg-protocol. The change is backwards compatible but results in a significant performance improvement across the board, with some queries as much as 50% faster. This is the first work to land in an on-going performance improvment initiative I'm working on. Stay tuned as things are set to get much faster still! 🚀

• Switch to using monorepo version of pg-connection-string. This includes better support for SSL argument parsing from connection strings and ensures continuity of support.
• Add &ssl=no-verify option to connection string and PGSSLMODE=no-verify environment variable support for the pure JS driver. This is equivalent of passing { ssl: { rejectUnauthorized: false } } to the client/pool constructor. The advantage of having support in connection strings and environment variables is it can be "externally" configured via environment variables and CLI arguments much more easily, and should remove the need to directly edit any application code for the SSL default changes in 8.0. This should make using [email protected] significantly less difficult on environments like Heroku for example.

• Same changes to pg impact pg-pool as they both use the same connection parameter and connection string parsing code for configuring SSL.

• Add maxUses config option.

note: for detailed release notes please check here

• Remove versions of node older than 6 lts from the test matrix. pg>=8.0 may still work on older versions but it is no longer officially supported.
• Change default behavior when not specifying rejectUnauthorized with the SSL connection parameters. Previously we defaulted to rejectUnauthorized: false when it was not specifically included. We now default to rejectUnauthorized: true. Manually specify { ssl: { rejectUnauthorized: false } } for old behavior.
• Change default database when not specified to use the user config option if available. Previously process.env.USER was used.
• Change pg.Pool and pg.Query to be an es6 class.
• Make pg.native non enumerable.
• notice messages are no longer instances of Error.
• Passwords no longer show up when instances of clients or pools are logged.

• This will likely be the last minor release before [email protected].
