Hi,Hackers,
I found that in the InjectionPointAttach function within the src/backend/utils/misc/injection_point.c file, the
variableis manually assigned a '\0' at the end, even though strlcpy already guarantees that the destination buffer will
benull-terminated and will not overflow.
The code modification is as follows:
```
/* Save the entry */
strlcpy(entry->name, name, sizeof(entry->name));
entry->name[INJ_NAME_MAXLEN - 1] = '\0'; <== Delete this line
strlcpy(entry->library, library, sizeof(entry->library));
entry->library[INJ_LIB_MAXLEN - 1] = '\0'; <== Delete this line
strlcpy(entry->function, function, sizeof(entry->function));
entry->function[INJ_FUNC_MAXLEN - 1] = '\0'; <== Delete this line
```
And in the injection_point_cache_add function within the same file, strlcpy(entry->name, name, sizeof(entry->name));
doesnot perform redundant assignment.
I have tested the change, and "make check" passed.
