I found a table pg_version_history in the public schema (which we don't
use). Does anyone know where this table comes from and what is it for?
Also I'd like to implement a code versioning for the functions. Is there
a package or a software to do this kind of things, so we can recover
from it a function in case it is deleted or overwritten with an old version?
Thanks
