How to upgrade a Heroku PostgreSQL database to a new plan

I started a project on a Hobby Dev plan (free, limit 10,000 rows), and then later needed to upgrade it to Hobby Basic ($9/month, limit 10,000,000 rows).

After assigning the new database, I had two databases attached to the application. They looked something like this:

• HEROKU_POSTGRESQL_OLIVE (postgresql-dimensional-3321) Old, free-tier (Hobby Dev) database

GraphQL Subscription with django-channels

Django channels are official way for implementing async messaging in Django.

The primary caveat when working with GraphQL subscription is that we can't serialize message before broadcasting it to Group of subscribers. Each subscriber might use different GraphQL query so we don't know how to serialize instance in advance.

We don't use that word here

There are some words which carry with them the baggage of sexism and ableism and so they're words we've chosen to avoid using within our community.

We realise that sometimes SlackBot might get a bit over-eager and correct you when you intentionally chose that word and it is appropriate. That's okay, but we find that in most cases, SlackBot's reminders help us choose our words with intention and promote a more inclusive and welcoming space.

There are plenty of other words that you can use which can still convey the meaning you're looking for. Sometimes it might require a bit of creativity, but trust us – it can be done.

We don't assume you were intentionally being sexist or ableist. Our language is littered with the legacy of unfortunate cultural baggage. You might not even believe that there's a problem with the word you used. That's cool, but we don't use that word here.

1. if you’re on (most modern distributions of) linux, forget that route(1) even exists (and throw ifconfig out in the same go) because it’s just absolutely frustrating. for probably 98% of what you need, ip(1) is the cool you care about

generally speaking, these will cover you: ip route, ip address, ip link

2. when dealing with routing problems (​even if just two hosts next to each other​), mtr > traceroute > ping is an order that’s useful for a lot of what you need

mtr is nice because you can just let it keep running. press d in its display to get a running history breakdown of packets. fantastic for intermittent issues!

traceroute is generally known already, but depending on the complexity of your networks in question you may want traceroute-nanog or similar other ones. some of these are ASN-aware, which is useful.
