### 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.
