How about creating another header file with the parallel changes and include it only in necessary places? Following are my observations, while going through the patch. +#if SIZEOF_DSA_POINTER == 4 +typedef uint32 dsa_pointer; +#else +typedef uint64 dsa_pointer; +#endif I feel the declaration of the above typdef can be moved into the section above if we going with the current move into postgres.h file. +/* + * tbm_alloc_shared + * + * Callback function for allocating the memory for hashtable elements. + * It allocates memory from DSA if tbm holds a reference to a dsa. + */ +static inline void * +pagetable_allocate(pagetable_hash *pagetable, Size size) Function name and comments mismatch?
