There is a possible sequence like this:

There are no platforms for which ALIGNOF_SHORT is different from 2.
I don't think there are any platforms we care about where ALIGNOF_INT
is different from 4. The cases of interest are ALIGNOF_DOUBLE,
ALIGNOF_LONG,

sizeof(int) maybe 8, but not 64.
And the configure option `--enable-integer-datetimes' may affect the data
layout.
Yes, typo. This has been checked by ControlFileData.enableIntTimes.

Yeah. It might be worth adding MAX_ALIGNOF to the set of configuration
data stored in pg_control, just to be sure you couldn't shoot yourself
in the foot that way.
PLEASE. :)
I am coming up with a patch of it. I think all ALIGNOF macros should be

The key problem I believe is the serials of ALIGNOF macros. Especially for

Not in my experience at least from going 32 bit intel to 64bit opteron.
