RE: Resetting recovery target parameters in pg_createsubscriber

Dear Alyona,

Thanks for updating the patch!
Sadly, your patch cannot be applied cleanly. Even after the manual merge, it could not
be built. Maybe `dbinfo` should be `dbinfos.dbinfo`. Obtained message is written in [1].
(cfbot seemed not to run correctly)

Regarding patch content, your patch restores the postgresql.auto.conf after the
command runs. Initially I felt that it is enough to set below GUCs becasue only
they are changed from the default. Is there a reason why you fully restore them?

```
recovery_target_inclusive    true
recovery_target_action        pause
recovery_target_lsn            ""
```

[1]
```
../postgres/src/bin/pg_basebackup/pg_createsubscriber.c: In function ‘main’:
../postgres/src/bin/pg_basebackup/pg_createsubscriber.c:2526:31: error: ‘dbinfo’ undeclared (first use in this
function);did you mean ‘dbinfos’?
 
 2526 |         reset_recovery_params(dbinfo, subscriber_dir);
      |                               ^~~~~~
      |                               dbinfos
```
