Simple select give wrong result when it uses the Bitmap Heap Scan path.
It's generally appropriate to mention which PG version you're working
with when you report a bug.
I was on 8.4 CVS Head, Next time will sure take care of this.
postgres=# explain select proname from pg_proc where proname like 'my_pro1';
QUERY
PLAN
--------------------------------------------------------------------------------
-------------
Bitmap Heap Scan on pg_proc (cost=4.26..8.27 rows=1 width=64)
Recheck Cond: (proname ~~ 'my_pro1'::text)
-> Bitmap Index Scan on pg_proc_proname_args_nsp_index (cost=0.00..4.26
row
s=1 width=0)
Index Cond: ((proname >= 'my'::name) AND (proname < 'mz'::name))
(4 rows)
Hmm, the ~~ condition should get treated as a "filter" not a "recheck".
I suppose I broke this somewhere ...
Oh ok.
