Gabriel Monsalvo (gmonsalvo@rentastucuman.gov.ar) reports a bug with a severity of 1
The lower the number the more severe it is.

Short Description
not usage index in subquerys o inner joins

Long Description
PostgreSQL makes sequencial scans when uses subqueries or inner joins like:
select * from ctacte where numoble in (select numoble from obligacion where numoble='2500001368995');
or:
select c.* from ctacte c inner join obligacion o on (c.numoble=0.numoble and o.objeto='00000007314')

we have ten million of records in our tables and you can imagine how much time that takes long....

Any solution? or idea?
