Example code bug: destination->data

The following documentation comment has been logged on the website:

Page: https://www.postgresql.org/docs/15/xfunc-c.html
Description:

38.10.2. Base Types in C-Language Functions

In the last example of the section, this line appears:

memcpy(destination->data, buffer, 40);

For me, this gave the following error:

error: ‘text’ {aka ‘struct varlena’} has no member named ‘data’

After tracking down the struct definition, I got the example working with:
destination->vl_dat instead. I assume this is correct, and that the member
name changed somewhere along the way.
