Why not support it for new chunks?? Users can be confused for the mix of chunks with and without the replica-identity, no? |

I agree with @fabriziomello. Especially since it'll create issues with update / delete statements on later created chunks. Tried to implement it. While it works, not sure this is the best way 😅 |
|
@fabriziomello I put this draft PR together as a proof-of-concept for @noctarius, thus supporting on new chunks is not yet implemented. |
|
@erimatnor feel free to apply my patch which will actually add the new table support :) |

Could you elaborate on the description in the commit message a little more. It is not very clear what this means.

A minor comment, but also something that probably needs to be checked.

We are printing full names elsewhere.

I'm happy to do a review, but I'm not deep enough into PG sources to find potential issues or oversights in the implementation 😅 |

Approving, but please print the full name of the table like we do elsewhere.
It is enabling standard PostgreSQL functionality that we previously blocked. I will elaborate, but probably best to refer to PostgreSQL docs. |

Add support for setting replica identity on hypertables via ALTER TABLE. The replica identity is used in logical replication to identify rows that have changed. Currently, replica identity can only be altered on hypertables via the root; changing it directly on chunks will raise an error.

This commit is a follow up of timescale#5515, which added support for ALTER TABLE ... REPLICA IDENTITY (FULL | INDEX) on hypertables. This commit allows the execution against materialized hypertables to enable update / delete operations on continuous aggregates when logical replication in enabled for them.

This release contains performance improvements for compressed hypertables and continuous aggregates and bug fixes since the 2.11.2 release. We recommend that you upgrade at the next available opportunity. This release moves all internal functions from the _timescaleb_internal schema into the _timescaledb_functions schema. This separates code from internal data objects and improves security by allowing more restrictive permissions for the code schema. If you are calling any of those internal functions you should adjust your code as soon as possible. This version also includes a compatibility layer that allows calling them in the old location but that layer will be removed in 2.14.0. **PostgreSQL 12 support removal announcement** Following the deprecation announcement for PostgreSQL 12 in TimescaleDB 2.10, PostgreSQL 12 is not supported starting with TimescaleDB 2.12. Currently supported PostgreSQL major versions are 13, 14 and 15.

The problem occurs because `currentEventTriggerState->currentCommand` is not set up since `AlterTableInternal` is called without calling `EventTriggerAlterTableStart`. This is because `AlterTableInternal` is called as part of a different statement, which do not "prepare" for an `AlterTable` correctly. Fixed it by properly adding the proper start and end calls for the event trigger on the underlying `AlterTable` to set the replica identity for a new created chunk introduced by timescale#5515. Fixes timescale#7406

Add support for setting replica identity on hypertables via ALTER
TABLE. The replica identity is used in logical replication to identify
rows that have changed.
Currently, replica identity can only be altered on hypertables via the
root; changing it directly on chunks will raise an error.
