Disabling Stripe extension breaks database
Getting your site back online, in phpmyadmin:


In table civicrm_extension, enable stripe (change 0 to 1)
In table payment_processor, disable any using stripe (change 1 to 0)


This should allow your site to load.

Deleting stripe (warning: stripe may be related to some transactions, check before doing this):


Make sure none of your donation pages are using stripe
Delete any payment methods using stripe
Delete the payment processor "stripe"
Disable extension "stripe"
Uninstall extension "stripe"


You'll still see it on the list of extensions with an install link. To get rid of it, you'll have to remove the com.drastikbydesign.stripe folder in /sites/default/files/civicrm/extension (or whatever your extensions directory is).
