Primary key Index Error

Postgres recovered from data folder , after that some queries shows error

select * from table2 order by app_id ; - its work ( 50000000 data)
select * from table2 order by app_id desc ; - its work

Here app_id contains binary index

select * from table2 order by id ; - its work ( 50000000 data)
select * from table2 order by id desc ; - shows following error

manoj[local] postgres ERROR: index "tbl2_id_pkey" contains unexpected zero
page at block 311121
manoj [local] postgres HINT: Please REINDEX it.

index "tbl2_id_pkey" is primary key

Reindex not pratical this table (250 GB data)

How i can solve this ?
