Easily remove revisions using wp-cli. First, get a list of revisions with:

$ wp post list --post_type='revision' --format=ids

This command will provide a list of revisions by post ID.

To remove those revisions, use to following command:

$ wp post delete $(wp post list --post_type='revision' --format=ids) --force

This command will provide feedback to stdout as Success: Deleted post XXX. Where XXX is the post ID of the deleted post. The --force flag may not be necessary, but was in my case since the command failed with the warning: Warning: Posts of type 'revision' do not support being sent to trash.
