Fixes of problems caused by incompatible Ubuntu package upgrades

Lately few Ubuntu 20.04 packages (mostly PostgreSQL related) upgraded and caused a HAF build/installation to fail on fresh/updated systems.

Fixes problem with

CREATE EXTENSION hive_fork_manager;
ERROR:  schema hive is not a member of extension "hive_fork_manager"
DETAIL:  An extension may only use CREATE ... IF NOT EXISTS to skip object creation if the conflicting object is one that it already owns.

Additionally has been fixed qualified names to few objects referenced by queries.
