Hi All, Functions like lappend_*() in list.c do not modify the second argument. So it can be qualified as const. Any reason why we don't do that? Is it because the target pointer ptr_value is not const qualified?
In my code, I am using lappend() and passing it the output of pq_getmsgstring() which returns const char *. The list is used to just collect these pointers to be scanned later a few times within the same function. So there is no possibility of freeing or changing area within the StringInfo. So the coding practice though questionable, is safe and avoids unnecessary pallocs. But SonarQube does complain about it. -- Best Wishes, Ashutosh Bapat
