Recently I saw some weirdness in an existing application when I upgraded a PECL module that the application depended on.
To figure out if that really was the problem, I wanted to downgrade the module to its previous version.
There is no opposite command to "upgrade" but you can instruct pecl to install a specific version of a module, using the -f switch to force pecl to overwrite newer modules.
