### 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.
