> _PG_fini
It should not work - see a doc
If the file includes a function named _PG_fini, that function will be
called immediately before unloading the file. Likewise, the function
receives no parameters and should return void. Note that _PG_fini will only
be called during an unload of the file, not during process termination.
(Presently, unloads are disabled and will never occur, but this may change
in the future.)
