Additionally, it may be necessary to replace the line `PG_MODULE_MAGIC`; in `contrib/snowflake/snowflake.c` with the
followingcode block:
```
PG_MODULE_MAGIC_EXT(
.name = "snowflake",
.version = PG_VERSION
);
```
In addition, the memory allocation code within the `snowflake_get` function:
```
nulls = palloc0(sizeof(bool) * tupdesc->natts);
values = palloc0(sizeof(Datum) * tupdesc->natts);
```
should be replaced with:
```
nulls = palloc0_array(sizeof(bool), tupdesc->natts);
values = palloc0_array(sizeof(Datum), tupdesc->natts);
```
