While looking into backend/storage/freespace/freespace.c, I noticed
that struct FSMAddress is passed to functions by value, rather than
reference. I thought our code practice is defining pointer to a struct
data and using the pointer for parameter passing etc.
typedef struct RelationData *Relation;
IMO freespace.c is better to follow the practice.
Maybe this has been allowed because:
typedef struct
{
int level; /* level */
int logpageno; /* page number within
the level */
} FSMAddress;
the struct size is 4+4=8 byte, which is same as 64 bit pointer. Still
I think it's better to use pointer to the struct because someday we
may want to add new member to the struct.
Best regards,
