Hi all,
I do not understand why postgreSQL estimates an index scan only half as fast as
a seq scan:

Hi,
I have the following simple query on a simple table:

Hi,
I am running PostgreSQL 8.1, on CentOS 5. I have two machines, same hardware,
with the same database layout,
they have different data, and the same query run 10 times as slow on one

Well,
I am from the hosting business, and can assure you, what you are looking for

This configuration requires specialists on the provider side, which are

Hi,
I tried this:

ERROR: invalid privilege type SELECT for database
The documentation seems to imply I need to grant SELECT
to each table separately. That's a lot of work, and what if
new tables are created?
Thanks,
Antonio

I have a column in a table that contains the name of another table,
