hmm, it looks like a leak in postgresql itself

Hello!
There is a lot of "safe" leaks of local memory in postgres and pg_probackup, because erroring out will free process memory.
In case of pg_probackup it is even simpler, because pg_probackup by nature is a one-shot process, so no point in freeing memory used, for example, for global parameters before exit.

But thank you for reminding us to check for memory leaks, will run some tests.

nevermind, I'll check with ASAN_OPTIONS="detect_leaks=0"
