Please change the pin from psycopg2-binary to psycopg2. The state of psycopg2-binary usage in Alpine Linux is abysmal and has nearly caused me production outages that I caught a little earlier in the pipeline.

Hi @dave-shawley,

I've read #631 about this and it seems to be vital, but let's release fixes by batches. I'm going to start working on #631 and #249 after 1.1 release as part of the next release.

OK?

[dave-shawley]

@Pliner , thanks for the quick response. Doing this in the next point release will be fine. This particular issue has been causing us a lot pain since we use Alpine Linux (non-glibc) as our primary deployment vehicle.

@asvetlov As we discussed, I'm going to release it as 1.1.0b0 first. Then after some testing in production I'm going to publish it as 1.1.0.
