I don't understand. The patch only affects configuration and SQL data type
code. It doesn't actually store the 64-bit commandid anywhere which would be
the actual hard part.
Sure it does, this is the significant part of the patch:
*** pgsql.orig/src/include/c.h 2008-03-02 13:44:45.000000000 +0100
--- pgsql-cid64/src/include/c.h 2008-03-04 21:05:23.000000000 +0100
*************** typedef TransactionId MultiXactId;
*** 382,388 ****
--- 382,392 ----
typedef uint32 MultiXactOffset;
+ #ifdef USE_64BIT_COMMANDID
+ typedef uint64 CommandId;
+ #else
typedef uint32 CommandId;
+ #endif
#define FirstCommandId ((CommandId) 0)
CommandId type is used in htup.h and elsewhere, which changes the
on-disk format.
