Hi Sushant,
i think the problem is that we miss check constraints.
We will implement asap
For the moment thank you to everybody for the excellent support!

What is the execution plan of a query is showing? Check whether it is
reading through all partitions.

Do you have non overlapping check constraints on the partitions by date to
allow the planner to exclude the child tables from needing to be looked at?
Hu guys,
we have a test machine with Postgresql 9.6.1 an about 800.000.000 record in a
table.
Table is partitioned by day, with indexes on partitioned table.
Also a simple query (for example i want to search log occurred in a specific
day), is immediate in tha partitioned table (table_2017_02_1

Use array_agg on column 2 along with group by on column 1 to build check arrays
and then use equals to compare with an array of your desired input values.
You should omit duplicates and order ascending both the data and the input to
ensure you are matching canonical forms.

Hi,
It's probably slow because you run many queries where a few would work:
DELETE FROM unassignedjobs WHERE jobid IN (6, 8 ,2, 99, 66)
But I wouldn't know how to build a query like that in C. A script in

But I have a further question. I've never seen the "~*" operator
