Description: pg_dump uses the first version of a primary key's name
when generating reports
Details:

reposted from pg-users, sorry for posting in the wrong place:

i believe i found a bug

psql> create table test_failure ( id integer primary key );
psql> alter table test_failure alter id rename to id_new ; # not relevant,
just illustrating the reason how i got to step 2
psql> alter table test_failure_pkey rename to test_failure_id_new_pkey;

$ pg_dump --schema-only -ttest_failure -Utest > test.sql

the pkey in the schema is added as 'test_failure_pkey' , not
'test_failure_id_new_pkey';

it happens whether or not you use 'alter table' or 'alter index' on the pkey
name
