What's Changed

Bug Fixes

  • Fix a bug in the maintenance of outer join views that include cross joins (Yugo Nagata)

    When an outer join view has a cross join in its children, incremental maintenance could not be performed properly.

    When an outer join view contains NULLs in join-condition columns, incremental maintenance could not be performed correctly.

About pg_ivm

pg_ivm is an extension module that provides Incremental View Maintenance (IVM) feature.

Incremental View Maintenance (IVM) is a way to make materialized views up-to-date in which only incremental changes are computed and applied on views rather than recomputing. pg_ivm provides a kind of immediate maintenance, in which materialized views are updated immediately after a base table is modified.
