supabase-mailer VS pg_cron

Supabase developer here. Just to clarify, Supabase has server-side functions (edge functions), emails can be sent with something like my repo here (https://github.com/burggraf/supabase-mailer) or through edge functions -- but you're right, while we do have the ability to send any auth-related emails built-in (sign up, sign in with magic link, MFA, reset password, etc.) we don't have an out-of-the-box solution for sending emails, that's why I wrote that repo. And lastly, it's quite easy to schedule tasks using pg_cron, which is built into every Supabase project by default.

Hello, I've tried these instructions https://github.com/burggraf/supabase-mailer/blob/main/Mail_Providers/Sendgrid.md when I tried to execute the first line INSERT INTO private.keys (key, value) values ('SENDGRID_API_KEY', 'aaaaaaaaaa'); in SQL editor (with my API key) in Supabase I've got this error: "Failed to run sql query: relation "private.keys" does not exist"

Here's a repo where I use the http extension extensively: https://github.com/burggraf/supabase-mailer

I was excited to find the supabase-mailer project, but unfortunately it seems that only the Mailgun provider is fully supported and working. Mailgun only has a 30 day trial, which didn't work for my needs.

You can't call the http function like that. You need to use a SELECT statement. See https://github.com/burggraf/supabase-mailer/blob/main/02A_send_email_mailgun.sql for an example: SELECT content INTO retval FROM http (('POST', ....etc

I'm not 100% sure you could do this with PostgreSQL functions, but you probably can. Since we have http access from these functions, I've written interfaces to some of the transactional email apis here: https://github.com/burggraf/supabase-mailer . (It's probably even easier if you use straight SMTP mailers.)

Not sure what you mean. I have a couple open-source repos on github that show you how you can send emails or text messages from a Postgres function using third-party providers. I also have a repo that shows how you could roll your own auth using functions. Assigning permissions and roles is definitely something you can do in functions -- that's standard postgres stuff....

[Postgres Extensions] pg_cron 1.5.2 (new projects only) now supports sub-minute schedules. PR

(Your PostgreSQL installation might already have pg_cron available, but if not, you would need to install it)

I’d set up citusdata/pg_cron in 14, so I’ll need to set that up in 15 as well.

Functions can be executed via a database query or on a regular schedule. Trigger functions are a special type of function that are covered in a previous article. They provide a way to execute an action based on a database event.

* extraction and loading: the psql-http PostgreSQL extension which is available in Supabase (but not all services like AWS RDS). Not sure how it works with OAuth but something to look into. * automation: use pg_cron to automate the ingest. * transformation: leverage Postgresql JSON functions.

A low-level alternative is using a PostgreSQL-side facility like https://github.com/citusdata/pg_cron - this, however, requires installing a PostgreSQL extension.

If you just want scheduling queries, you can use this https://github.com/citusdata/pg_cron
