I'm ok to remove the check "values[i] != NULL", but think that it's better to keep the
other check "*(values[i]) != '\0'" as it is. Because *(values[i]) can be null character
and it's a waste of cycles to call process_pgfdw_appname() in that case.
Thanks for revisiting.
#1. use "[unknown]"
#2. add the check but not use "[unknown]"
#3. don't add the check (i.e., what the current patch does)
For now, I'm ok to choose #2 or #3.
As I said before, given that we don't show "unkown" or somethig like
as the fallback, I'm fine with not having a NULL check since anyway it
bumps into SEGV immediately. In short I'm fine with #3 here.
Yep, let's use #3 approach.
