pgsql-server: Fix oversight in recent rowtype-handling improvements:

Log Message:
-----------
Fix oversight in recent rowtype-handling improvements: transformTargetList
should recognize 'foo.*' when the star appears in A_Indirection, not only
in ColumnRef.  This allows 'SELECT something.*' to do what the user
expects when the something is an expression yielding a row.
