I believe moving "[ ONLY ]" to the definitions of table_and_columns below, as you did with "[ * ]", might be better to be consistent with other places (see [1])
+ if ((options & VACOPT_VACUUM) && is_partitioned_table && ! include_children)
There are also some issues with coding conventions in some places (e.g. the space between "!" and "include_children" abode). I think running pgindent would resolve such issue in most places.
