This is the first release of pg_ivm extension module.
pg_ivm provides Incremnetal View Maintenance (IVM) feature for PostgreSQL.
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.
Compatible with PostgreSQL 14
Supporting Selection-Projection-Join, and DISTINCT
