While working on the other patch that fixed wrong "const" usage [1], I
found the function:
```
GinPostingList *
ginCompressPostingList(const ItemPointer ipd, int nipd, int maxsize,
int *nwritten)
```
uses "const" unnecessarily. Because it needs to assign an element of
"ipd" to the returned structure "GinPostingList->first" and "first" is a
mutable "ItemPointerData *", so that "ipd" cannot be of const pointer.
I have committed a fix for this together with the other one.
The code you are referring to here is:
result->first = ipd[0];
This is a value copy, so this does not violate the immutability of ipd.
So the const in the function prototype was the right idea, but in the
wrong place of course.
