how to install PostgreSQL extensions?

[alissonduck]

I created a PostgreSQL v18 cluster with Everest and I need to install the "pg_search" and "hypopg" extensions.

However, the PostgreSQL container is read-only.

How can I install these extensions?

We are working on it. Right now there is no straighforward way to do that. The workaround is to use Percona Operator capability to do it:
https://docs.percona.com/percona-operator-for-postgresql/2.8.0/custom-extensions.html

that would require changing the custom resource.

BTW better use https://github.com/openeverest/openeverest for such issues, not the docs :)
