[PATCH v6 2/2] Add a --outdated option to reindexdb 3+ messages / 3 participants [nested] [flat]
* [PATCH v6 2/2] Add a --outdated option to reindexdb @ 2021-02-24 17:33 Julien Rouhaud <[email protected]> 0 siblings, 0 replies; 3+ messages in thread From: Julien Rouhaud @ 2021-02-24 17:33 UTC (permalink / raw) This uses the new OUTDATED option for REINDEX. If user asks for multiple job, the list of tables to process will be sorted by the total size of underlying indexes that have outdated dependency.

I went ahead and closed it, and then started two new open items for the two new issues --- one is about assert failure and wrong query results due to incorrectly removing PHVs, the other is about inconsistent nulling bitmap in nestloop parameters.
