pgenv switch`

pgenv, a simple but great shell script that helps managing several PostgreSQL instances on your machine, have been improved in the last days.

Thanks to the contribution of Nils Dijk @thanodnl on GitHub, there is now a new command named switch that allows you to quickly prepare the whole environment for a different PostgreSQL version without having to start it.
The problem, as described in this pull request was that the use command, trying to be smart, starts a PostgreSQL instance once it has been chosen. On the other hand, switch, allows you to pre-select the PostgreSQL instance to use without starting it. This is handy, for example, when you want to compile some code against a particular version of PostgreSQL (managed by pgenv) but don’t want to waste your computer resources starting up PostgreSQL.
To some extent, switch can be thought as an efficient equivalent of:



The command has been implemented as a subcase of use, but while use does fire up an instance, switch does not.
However, in the case an instance is already running, switching to a new instance will stop the previously running one!

Other minor contributions

If you have pgenv on the radar, you probably have seen another release in the last days, that covered a bug fix spot by Nils Dijk about the management of the configuration.

Conclusions

pgenv keeps growing and adding new features, and is becoming a more complex beast than it was in the beginning. Hopefully, it can help your workflow too!
