4) Your problems with tsearch and timestamp etc raise an interesting problem. We don't need to mark this in pg_control because it's a purely a run-time
   issue and doesn't affect on-disk storage. However it does affect ABI
   compatibility with modules. Perhaps it should be added to

I am looking into it.

Do you think it's actually needed?
PG_MODULE_MAGIC_DATA contains the server version
the external module was compiled for. This patch won't go to
older versions, so it's already protected from the unconditional
float4 change. And because you can't mix server and libraries
with different bitsize, it's protected from the conditional int64,
float8, etc. changes.
