At my current workplace, view definitions (which are very old-school with
revision history etcetera recorded in comments) are stored in PL/PgSQL functions
which are updated and executed whenever views are modified. I'm looking at
adding a wrapper function to automatically detect and recreate dependencies,
not sure how well that would work. We keep track of schema changes via
pg_extractor[1] which integrates quite nicely with GIT.
