Re: 8.4, One-Time Filter and subquery ( ... FROM function() union all ... ) - Mailing list pgsql-hackers

Oh, now problem with simple query:

8.4.0 from Debian
explain analyze select i from t where i >= 10 and i = 1;                                    QUERY PLAN
------------------------------------------------------------------------------------Result  (cost=0.00..0.01 rows=1
width=0)(actual time=0.002..0.002 rows=0 loops=1)  One-Time Filter: falseTotal runtime: 0.030 ms
 

CVS HEAD
explain analyze select i from t where i >= 10 and i = 1;                                           QUERY PLAN
---------------------------------------------------------------------------------------------------Seq Scan on t
