Update bgw job table when altering procedure #7409

mkindahl · 2024-10-29T20:17:29Z

This deals with the following modifications to the name of a procedure
used by a background job:

If a procedure that exists in the jobs table is renamed, the corresponding names in the table will also be changed.
When a procedure that is used for a background worker job is moved to a different schema, modify the job entry as well.
When a schema is renamed, rename the schema name in the procedures as well.
When a schema is dropped and there are procedures used by jobs, it will either remove the entry or throw an error, depending on whether CASCADE or RESTRICT is in effect.
When a procedure or function used by a job is dropped, it will error out or delete the job depending on whether CASCADE or RESTRICT is in effect.

This release introduces the ability to add secondary indexes to the columnstore, improves group by and filtering performance through columnstore vectorization, and contains the highly upvoted community request of transition table support. We recommend that you upgrade at the next available opportunity. **Highlighted features in TimescaleDB v2.17.0** * The ability to add secondary indexes to the columnstore through the new hypercore table access method. * Significant performance improvements through vectorization (`SIMD`) for aggregations using a group by with one column and/or using a filter clause when querying the columnstore. * Hypertables support triggers for transition tables, which is one of the most upvoted community feature requests. * Updated methods to manage Timescale's hybrid row-columnar store (hypercore) that highlight the usage of the columnstore which includes both an optimized columnar format as well as compression. **Dropping support for Bitnami images** After the recent change in Bitnami’s [LTS support policy](bitnami/containers#75671), we are no longer building Bitnami images for TimescaleDB. We recommend using the [official TimescaleDB Docker image](https://hub.docker.com/r/timescale/timescaledb-ha) **Deprecation Notice** We are deprecating the following parameters, functions, procedures and views. They will be removed with the next major release of TimescaleDB.

This release introduces the ability to add secondary indexes to the columnstore, improves group by and filtering performance through columnstore vectorization, and contains the highly upvoted community request of transition table support. We recommend that you upgrade at the next available opportunity. **Highlighted features in TimescaleDB v2.18.0** * The ability to add secondary indexes to the columnstore through the new hypercore table access method. * Significant performance improvements through vectorization (`SIMD`) for aggregations using a group by with one column and/or using a filter clause when querying the columnstore. * Hypertables support triggers for transition tables, which is one of the most upvoted community feature requests. * Updated methods to manage Timescale's hybrid row-columnar store (hypercore) that highlight the usage of the columnstore which includes both an optimized columnar format as well as compression. **Dropping support for Bitnami images** After the recent change in Bitnami’s [LTS support policy](bitnami/containers#75671), we are no longer building Bitnami images for TimescaleDB.

This release introduces the ability to add secondary indexes to the columnstore, improves group by and filtering performance through columnstore vectorization, and contains the highly upvoted community request of transition table support. We recommend that you upgrade at the next available opportunity. **Highlighted features in TimescaleDB v2.18.0** * The ability to add secondary indexes to the columnstore through the new hypercore table access method. * Significant performance improvements through vectorization (`SIMD`) for aggregations using a group by with one column and/or using a filter clause when querying the columnstore. * Hypertables support triggers for transition tables, which is one of the most upvoted community feature requests. * Updated methods to manage Timescale's hybrid row-columnar store (hypercore) that highlight the usage of the columnstore which includes both an optimized columnar format as well as compression. **Dropping support for Bitnami images** After the recent change in Bitnami’s [LTS support policy](bitnami/containers#75671), we are no longer building Bitnami images for TimescaleDB.
