This was missing an include of xlogdefs.h in pg_subscription.h, thus failing
in headerscheck. See e.g.
https://buildfarm.postgresql.org/cgi-bin/show_log.pl?nm=crake&dt=2022-03-22%2022%3A22%3A05

I've pushed the trivial fix for that. I'll propose adding headerscheck to CI /
cfbot.

Greetings,

Andres Freund
