feat: Add pg_cron and Postgis

[philippemnoel]

Ticket(s) Closed

• Closes #N/A

What

We ship with these two extensions in ParadeDB Dockerfile as well, but had forgotten to add them to our Helm Chart setup. This fixes that.

TODOs

• Add comment for \c -- Not necessary anymore: https://trac.osgeo.org/postgis/ticket/5125
• Test that pg_cron and postgis work, and that the cron.database_name is correct
• Add automatic install of pg_cron
• Update instructions for testing
• Final manual test on Minikube cluster

I think you'll also need to modify this test: https://github.com/paradedb/charts/blob/main/charts/paradedb/test/postgresql-cluster-configuration/01-non_default_configuration_cluster.yaml

and it's assertion here:

https://github.com/paradedb/charts/blob/main/charts/paradedb/test/postgresql-cluster-configuration/01-non_default_configuration_cluster-assert.yaml

You mean this?

      postInitSQL:
        - CREATE TABLE mytable (id serial PRIMARY KEY, name VARCHAR(255));

To check that create extension pg_cron; works?

[itay-grudev]

@philippemnoel Yes. The assertion should be that both your statement and the custom statement are set:

      postInitSQL:
        - CREATE EXTENSION IF NOT EXISTS pg_cron;
        - CREATE TABLE mytable (id serial PRIMARY KEY, name VARCHAR(255));

Thank you!
