Re: Re: BUG #16702: inline code and function : when use dynamic name for rowtype, there is some bug!

I've lost something in translation.  There is no bias (not sure what that means in this context) or variability/ambiguity here.  The thing in front of %RowType is always an identifier - specifically, a table.  That your function also has a variable of the same name is immaterial to PostgreSQL since none of the variables in the function are ever considered when it is expecting/required-to-have an identifier to fulfill the syntax.  This is well-defined in PostgreSQL pl/pgsql and so the observed behavior is not buggy.

"select tbl%rowtype into a%rowtype" is effectively (cast tbl%rowtype as a%rowtype) which is a well-defined and the user is responsible for ensuring the two rowtypes are compatible. "tbl" and "a" are compatible, "b" and "a" are not, which your original post demonstrates.
