Hi,
I have some comments for the v5 patch:
1.
```
+ base_dir = (char *) pg_malloc0(MAXPGPATH);
+ len = snprintf(base_dir, MAXPGPATH, "%s/%s", subscriber_dir, PGS_OUTPUT_DIR);
```
Before these lines, I think we should use
'canonicalize_path(subscriber_dir)' to remove extra unnecessary
characters. This function is used in many places like initdb.c,
pg_ctl.c, pg_basebakup.c, etc
2.
I also feels that there are many global variables and can be arranged
as structures as suggested by Kuroda-san in [1]
Thanks and Regards
Shlok Kyal
