Postgres 16

[victorhazbun]

Hey,

I was wondering if you are open for a PR that introduces PG 16. Would you be able to merge soon?

Something like this:

{
    "name": "PostgreSQL Client",
    "id": "postgresql-client",
    "version": "1.0.0",
    "description": "PostgreSQL is a powerful, open source object-relational database system that uses and extends the SQL language combined with many features that safely store and scale the most complicated data workloads.",
    "options": {
        "version": {
            "type": "string",
            "proposals": [
                "13",
                "14",
                "15",
                "16"
            ],
            "default": "13",
            "description": "Select the major version of postgres"
        }
    },
    "installsAfter": [
        "ghcr.io/devcontainers/features/common-utils"
    ]
}

@robbert229 is there a new release needed for these changes to work? Latest version is 1.0.0 but I'm not sure if the changes from my PR will be there.

I will take a look at cutting a release today
