Checking out the workflow https://github.com/postgresml/pgcat/blob/main/.github/workflows/generate-chart-readme.yaml Has this ever worked? I don't think there is a README.md for the chart? Also the paths are a bit funky if this is expected to work. For example

Generalizing the secret lookup functionality that was added in postgresml#753 to work for `admin_password`, `auth_query_password`, `server_password`, and really any other one. It works by creating a `pgcat.password` template which expects an object containing values for the `password` and `secret` keys. `password` is a literal value normally supplied via `.Values.xyz` value. `secret` is an object with a key and name property that effectively functions like a _secretKeyRef_. When the literal value is not blank, that is used. Otherwise an attempt is made to lookup to supplied key from the named secret and use that. This is exactly how the current implementation of `user_password` works, which avoids any breaking changes. See the function definition for more details. > Note: it seems like `user_passwordSecret` was added (camelCase name) while all the other ones are _snake_case_. I elected to use snake case for the new values, but left `user_passwordSecret` as is to avoid any breaking changes.

What
min_pool_sizeandsever_lifetimeconfigurable under the user section.Why
server_lifetimegets overwritten by the hardcodedserver_lifetimevalue under the user section, which can cause confusion. So, if it is not explicitly set in thevalues.yaml, it should not be set per user at all, and the global value should be respected.min_pool_sizeshould also be configurable and if not set the default value will be3as per the original version of the chart.server_tls = true.statement_timeouthas default value of 0 and should be explicitly enabled.
