1) The recent patch removed the function header comment where
generated column is specified, that change is required:
@@ -511,7 +511,6 @@ pub_collist_validate(Relation targetrel, List *columns)
{
Bitmapset *set = NULL;
ListCell *lc;
- TupleDesc tupdesc = RelationGetDescr(targetrel);

foreach(lc, columns)
{
@@ -530,12 +529,6 @@ pub_collist_validate(Relation targetrel, List *columns)

column \"%s\" in publication column list",
colname));

- if (TupleDescAttr(tupdesc, attnum - 1)->attgenerated)
- ereport(ERROR,
-
errcode(ERRCODE_INVALID_COLUMN_REFERENCE),
- errmsg("cannot use generated
column \"%s\" in publication column list",
- colname));
-

2) This change is no more required as get_publications_str changes are
removed now:
