Examples of how to use a non-default version of postgres

[cprice404]

It would be nice to have some example manifests in the "tests" directory which demonstrated how to use a non-default version of postgres. So, e.g., on CentOS6, the default is postgres 8.4. However, if you add the postgres RPM package repos, you can install postgres 9.1. The module supports this but we don't illustrate how you'd go about configuring your setup to take advantage of it.

Looking at the source code its not obvious to me how to do this. If some gives me some hints I'll submit a pull request and add it to the tests and README.

So, peeking at the existing manifests, it looks like there is a little bit of missing plumbing. What probably need to happen is that types like postgresql::database need to allow an additional parameter called pg_version or something to that affect; it would default to the value of $::postgres_default_version. Then, we need to get rid of all of the direct references to $::postgres_default_version ; unfortunately, quite a few of those are in params.pp... so those might need to be moved into config.pp instead, since params.pp is inherited.

Maybe not quite as easy as I thought when I originally added the issue.

There is in an example of this in the tests directory now, as of pull req #43. Could still use some more examples and docs though, so I'll leave this open for the moment.

This needs at least one more example, for debian.

There are examples in the tests directory now. The example code is the same for redhat/debian.
