 * qualify_table_stmt.c
 *	  Functions specialized in fully qualifying all table statements. These
 *	  functions are dispatched from qualify.c
 *
 *	  Fully qualifying table statements consists of adding the schema name
 *	  to the subject of the table as well as any other branch of the
 *	  parsetree.
 *
 *	  Goal would be that the deparser functions for these statements can
 *	  serialize the statement without any external lookups.
