expo-auth-session example
/* An example app that uses expo-auth-session to connect to Azure AD (or hopefully most providers)
Features:

- uses zustand for global access to the token / logout
Based on [this gist](https://gist.github.com/thedewpoint/181281f8cbec10378ecd4bb65c0ae131)

Use trigger to change `updated_at` on all PostgreSQL tables
#
# Delete previous function definition (if exists)
#
DROP FUNCTION IF EXISTS before_update_updated_at() CASCADE;
#
# Create function to update updated_at timestamp if changed values on update
#
CREATE OR REPLACE FUNCTION before_update_updated_at() RETURNS trigger AS
