Hi!

I try to catch a DropStmt and convert it to a Rename Stmt, like petere's
pg_trashcan, but i don't like to create new schema. I only like to
rename the table in case of a drop table query.
Is this possible with something like:

ProcessUtility (Node * parsetree,
const char *queryString,
ParamListInfo params,
bool isTopLevel,
DestReceiver * dest, char *completionTag)

{
if (nodeTag(parsetree) == T_DropStmt)
{
DropStmt *stmt = (DropStmt *) parsetree;
if (stmt->removeType == OBJECT_TABLE)
{
RenameStmt *newstmt = makeNode(RenameStmt);
newstmt->objectType = stmt->removeType;
newstmt->newname = new_name;
parsetree = (Node *) newstmt;
}
(*prev_ProcessUtility) (parsetree, queryString, context, params,
dest, completionTag);
}

regards
