Cannot enable chunk skipping after upgrading to 2.17.1

TimescaleDB and PostgreSQL
1

Hi,

I upgraded Timescale from 2.16.0-dev to 2.17.1 and have been trying to use chunk skipping on a compressed hypertable.

I do select enable_chunk_skipping ('hypertable_name', 'column_to_skip') but get this error:

chunk skipping functionality disabled, enable it by first setting timescaledb.enable_chunk_skipping to on

I don’t see anything in the documentation on this. Is this a parameter in the postgresql.conf file or somewhere else?

Hello @kunjmehta , if your user is admin, you can enable it directly from the session, but for all the system:

alter system set timescaledb.enable_chunk_skipping to on;

Or just make it in the actual session:

set timescaledb.enable_chunk_skipping to on;

You can also put it on postgreql.conf in case you want to persist it for all databases.

Thanks for the information, sadly I also had to find this post because I came across the exact problem and its still not part of the docs, nowhere to be found.

Thanks for the feedback, I’ll share it with our docs team to make sure we have it up to date.
