PostgreSQL regression corpus
Copyright (c) 1996-2026, PostgreSQL Global Development Group
The Gres conformance pg_regress corpus under
crates/gres-conformance/corpus-regress/ includes files vendored from the
PostgreSQL project (https://github.com/postgres/postgres) under the
PostgreSQL License. Each adopted file carries a provenance header naming the
tag it was fetched from: boolean and int4 were vendored at tag REL_18_0, and
every other adopted file at tag REL_18_4 (the tag matching the pinned
PostgreSQL 18.4 conformance oracle). The boolean and int4 sources are
byte-identical between the two tags.
