Hi Gyan,
I reviewed/tested the patches, please find below comments for v13-002 patch -
File: pg_createsubscriber.c
1)
+
+ if ((internal_log_file_fp = logfile_open(internal_log_file, "a")) == NULL)
+ pg_fatal("could not open log file \"%s\": %m", internal_log_file);
+
IIUC, the pg_fatal() call here seems unreachable as the function
logfile_open() itself calls pg_fatal() and exits if it fails to open
the file.
I think it should just be -
internal_log_file_fp = logfile_open(internal_log_file, "a");
Please correct me if I'm missing something.

2)
+ if (opt->log_dir != NULL)
+ out_file = psprintf("%s/%s/%s.log", opt->log_dir, log_timestamp,
SERVER_LOG_FILE_NAME);
+ else
+ out_file = DEVNULL;
+
+ cmd_str = psprintf("\"%s\" -D \"%s\" >> \"%s\"", pg_resetwal_path,
+ subscriber_dir, out_file);
Similar to internal_log_file, why are 'out_file' and 'cmd_str' above not freed?

Above introduces newlines in result log, test 29 and 32 looks like -
[14:46:59.071](0.639s) ok 28 - run pg_createsubscriber --dry-run on node S
[14:46:59.071](0.000s) ok 29 -
[14:46:59.071](0.000s) # pg_createsubscriber_server.log file was created
[14:46:59.071](0.000s) ok 30 - pg_createsubscriber_server.log file not empty
[14:46:59.071](0.000s) ok 31 - server reached consistent recovery state
[14:46:59.072](0.000s) ok 32 -
[14:46:59.072](0.000s) # pg_createsubscriber_internal.log file was created
[14:46:59.072](0.000s) ok 33 - pg_createsubscriber_internal.log file not empty
These should be single-line results similar to others.
