Thanks! But that code broke tests :( See https://travis-ci.org/guedes/pgvm/builds/3938373/#L98

Ah... Your test wait exit code different that I wrote. Ok, I will fix and commit again. 👍

guedes, I check the Travis test and I believe that the test need to change.

# failed: match = /^version 999 is not installed$/ 

This case will be more right pgvm to return:

$ pgvm use 999
Select a specific version of PostgreSQL to use.
Usage: pgvm use X.Y.Z
where X.Y.Z is the semantic version of a installed PostgreSQL
E.g.
   ~$ pgvm use 9.1.4
TIP: you can use 'pgvm list' to see the PostgreSQL
     installations available.

This because in return said as would to use argument. What do you think?

[guedes]

But we should tell user when a version passed as argument isn't installed. Feel free to change the tests to rely on that, but we should avoid broke things. We should remember that in the future user will call use passing a major or middle version to it like use 9 or use 9.2.

[fike]

Sure. I believe that is possible to make

use 9

this now. I will be work this.

[guedes]

Nice, please fix the broken test "$ pgvm use 999" and create a new test to this issue.

Thanks!
