Draft: fixes BUG-54768: error reading functions if oid excedes max int value

When oid excedes the maximum value for int in Java, an error is thrown reading functions from pg catalog.

Changed to read them as long instead of integer.

To Do

• DBSM tests

  • Currently no code returns value when this param is used. To decide whether a test can be created to force it.

• Try (backoffice): https://builds.openbravo.com/view/try/job/try-init/3384/

• Look for other occurrences of the same problem

• Prepare a reproducer (?). Idea from @huehner :

  Loop 2M times:

  create + drop 'some simple db objects' should not matter which
  afterwards => create function + check oid (sql in the issue)

• Backport to customer
