Hi,
I want to delete duplicates in my table. I've dropped the unique constraint to
insert my data.
My id value is a hash calculated witch the values of the two other columns.
So I want to delete all columns, which are indentical, but keeping one.
DELETE FROM table t1 USING table t2 WHERE t1.id
With C as (
Select row_number() over partition by (list, all, columns, here order by
oid) as rn
)
Delete
>From C
Where rn > 1;

Hello all,
A few questions about materialized views.
When I refresh a materialized view, is it a DELETE/INSERT behind the
scenes?
Do we need to vacuum to reclaim space?
If a query is executed against the view when the refresh is happening, will
the query see the data before the refresh started?
Doe
To answer my own question, I saw this thread -
http://postgresql.1045698.n5.nabble.com/Efficiency-of-materialized-views-refresh-in-9-3-td5762618.html
I think that does answer my questions. Nothing has changed?
Regards,
Jayadevan

Hello,
I'm working on an upgrade to our database cluster, attempting to move from 8.4

Does postgres have an equivalent C level (or ODBC) parameter so you can
use IPC for local to db server only code?

Thanks for the responses. I found that I was using an older version of psql
(one that got installed when I installed Cygwin on my windows box. I
changed it so now the \d+
gives me the description but \d and \dt still gives me "No relations
found" so I must be using those incorrectly. Thanks
