OK, finally got back around to trying to get postresql working with the
storage subordinate and the block-storage-broker.

But adding the relations causes the following error (I hope this stack
trace is shown better for you than me):

google tells me that the python hmac function doesn't accept unicode,
but I'm not sure where that is coming from.

I have taken the precise charms for postgresql, storage, and
block-storage-broker and deployed them on trusty for this.

Anyone got suggestions?
