[pmg-devel] [PATCH pmg-api 1/3] dbtools: grant permissions public schema for created databases

[Dominik Csapak]

since postgres 15, the public schema is not world writeable anymore for
security reasons. In our environment, where the db is not externaly
reachable and no database users should exists except the ones we create,
we can safely give the permissions again to be able to use
the root/www-data user without modification of the remaining
code/privileges for postgres.
