memory management in Ada: tedious without GC?

I'm mostly soliciting answers from Ada programmers who know C++ RAII
well (Skip this if you use the words "C" and "C++" interchangeably,
please. Your answers will be misleading at best):

As I understood from reading the Memory Management section of
Wikibooks on Ada, Ada's memory management facilities are roughly
equivalent to

a. C++-like "new"
b. C++-like "delete"
c. Java-like "finally"
d. your implementation may or may not have GC

Did I misunderstand?

To me, this seems much, much more error-prone and tedious that C++'s
RAII approach, where you almost never have to worry about deallocation
(i.e. "b" and "c" above), even in the presence of exceptions, unless
you have GC. Besides, RAII applies to a bunch of other things, like
thread locks, database connections, files - not just memory.
