Alter table set statistics with partitioned tables

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



I have had to bump the stats on a partitioned table in order to get the planner to use an index over a seqscan. This has worked well in making the system perform where it needs to as it reduced one query's execution from > 45 seconds to < 1 second.

The one problem I have run into is that when I create a new child table / table partition, the stats value (attstattarget in pg_attribute) does not get carried over from the parent - instead the system default (-1) is set. Is it supposed to behave this way - meaning that I need to explicitly define the custom value for each child table? Or is there a way for this to be implicitly copied when the child table is created?

I prefer not to change the system default on all the tables in the database because the value needs to be increased for one case.

Thanks,

Kevin
