Agreed. Postgres-XL code is under the Postgres license:
Postgres-XL is released under the PostgreSQL License, a liberal Open
Source license, similar to the BSD or MIT licenses.
and even says they want it moved into Postgres core:
https://www.postgres-xl.org/2017/08/postgres-xl-9-5-r1-6-announced/
Postgres-XL is a massively parallel database built on top of,
and very closely compatible with PostgreSQL 9.5 and its set of advanced
features. Postgres-XL is fully open source and many parts of it will
feed back directly or indirectly into later releases of PostgreSQL, as
we begin to move towards a fully parallel sharded version of core PostgreSQL.
so we should understand what can be used from it.
