That's built by Devrim et al (copied) and not by the pygres team.

I'm not sure, but there's also features which require recent client library, so
there's a balance between 1) not requiring brand new dependencies; and 2)

This is one new feature:
| New query method memsize() that gets the memory size allocated by the query (needs PostgreSQL >= 12 on the client).
