Postgresql 12.5.
https://www.postgresql.org/docs/12/ddl-partitioning.html mentions creating
indices on children, and then attaching them to a table which previously had
CREATE INDEX ... ONLY ON executed.
Can I do something similar on an existing table (for example, on a heavily

I second this. While I'm not all that familiar with partitioning I am
readily getting the feeling that whether or not partitioning is used

It sounds like you are wanting to union all the results of the query you
gave, with the results of a similar query where modified_date >=
'2021-03-01 08:16:13.589' and created_at < '2021-03-01 08:16:13.

We've got a table partitioned by month range (FOR VALUES FROM ('2011-07-01')

one at a time. Whenever it's failed due to a FK constraint (and there are

Hi Michael,
Yes I have a btree index on the *modified_date* column currently.
SELECT * FROM partitioned_table where
A ='Value'
AND created_date >= '2021-03-01 08:16:13.589' and created_date <=
'2021-04-02 08:16:13.589' ORDER BY viewpriority desc OFFSET 0 ROWS FETCH
NEXT 200 ROWS ONLY;

Do you have an index on the "updated_at" field and found that the query is
too slow? Do you have an example query?
Hi All,
Please find my use case below and suggest the appropriate solution:
We have done declarative partitioning over our table A based on some key
and further range sub partitioned each partition on the basis of
createddate range of 90 days.
In the search query to display last 90 day data , I
Right to the point ==> set client_min_messages=error; Solved it

Hm, for me there are such warnings on 11.x too. Not as many --- it
looks like indexes are mentioned as well in 12.x. But it's never

Hi,
Good old "analyze;" will run smoothly on 11.5...
But on 12.6 will skip and warn on any pg_catalog/information_schema table.
Pg_catalog is on Usage only on both databases (11.5 and 12.6).
Questions: 1. Has the behavior changed in 12.6? 2.How can I analyze on public
tables (No syntax lik

I'm not sure if the disable-triggers option of data-only restore disable
