Your problem seems strange as it has never been previously reported for anyone else that has _successfully_ set up partioning.

Perhaps is you provide just a little bit more detail we might be able to help you.

Useful and needed information would be:

1. Version of PostgreSQL

2. Operating System

3. Table structure for partitioned table

4. Trigger function and trigger used for insert

5. The actual insert statement.

Hi All;

we setup partitioning for a large table but had to back off because the return status (i.e: "INSERT 0 1") returns "INSERT 0 0" when inserting into the partitioned table which causes the ORM tool to assume the insert inserted 0 rows.  Is there a standard / best practices work around for this?

Thanks in advance

And which ORM are you using.

I take it the problem is that the ORM is saying "zero rows inserted" and that's um, er, upsetting the client ( which might decide to retry and then generates an error for non-unique key or some such noise)

I reserve the right to fantasize.  Whether or not you
wish to share my fantasy is entirely up to you.

I think they are using Ruby, turns out the application is checking this and throwing an error (and rolling back) when it detects no rows inserted
