Signed vs Unsigned (take 2) (src/backend/storage/ipc/procarray.c)

Hi,

With the recent changes at procarray.c, I take a look in.

msvc compiler, has some warnings about signed vs unsigned.

So.

1. Size_t is weird, because all types are int.

2. Wouldn't it be better to initialize static variables?

3. There are some shadowing parameters.

4. Possible loop beyond numProcs?

- for (size_t pgxactoff = 0; pgxactoff < numProcs; pgxactoff++)
+ for (int pgxactoff = 0; pgxactoff < numProcs; pgxactoff++)

I think no functional behavior changed.

Patch attached.

best regards,
