IVM Development Group is pleased to announce the release of pg_ivm 1.1.

Changes since the v1.0 release include:

• Adds support for PostgreSQL 13

• Add support for aggregates

  In this release, built-in count, sum, and avg are supported.

• Add support for TRUNCATE on base tables

• Add refresh_immv() function

  This is a function to refresh IMMV like REFRESH MATERIALIZED VIEW command. It has a boolean parameter corresponding to the WITH [NO] DATA option. When this flag is set false, the IMMV gets unpopulated, and immediate maintenance on the IMMV is disabled.

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.
