[patch] ALTER RENAME and indexes

The attached patch works for my case...

regression=# create table test (id serial, col1 varchar(64));
NOTICE:  CREATE TABLE will create implicit sequence 'test_id_seq' for SERIAL column 'test.id'
NOTICE:  CREATE TABLE/UNIQUE will create implicit index 'test_id_key' for table 'test'
CREATE
regression=# create index i_t_c on test(col1);
CREATE
regression=# alter table test rename col1 to col2;
ALTER
regression=# \d test                                  Table "test"Column |         Type          |

wooohoo!!!  Of course, it would be best if someone else looked this
code over, because I get the feeling there is an easier way to get
this done.  The only thing I can say is that it solves my problem
and does not /appear/ to create any others.

cheers. Brent

p.s., I appreciate the gurus not jumping in with the quick fix --
The experience has been fun :-)
