ColumnDef column definition (used in various creates)

If the column has a default value, we may have the value expression in either "raw" form (an untransformed parse tree) or "cooked" form (a postparseanalysis, executable expression tree), depending on how this ColumnDef node was created (by parsing, or by inheritance from an existing relation). We should never have both in the same node!

Similarly, we may have a COLLATE specification in either raw form (represented as a CollateClause with arg==NULL) or cooked form (the collation's OID).

The constraints list may contain a CONSTR_DEFAULT item in a raw parsetree produced by gram.y, but transformCreateStmt will remove the item and set raw_default instead. CONSTR_DEFAULT items should not appear in any subsequent processing.

Fields
