I wonder how many of these changes pass the compilation only because the
header you're removing is indirectly being included via another header.
In this particular case, it's because slot.h includes walreceiver.h
which includes walsender.h, so this removal has no effect.

Maybe play with the script here
https://postgr.es/m/202510021240.ptc2zl5cvwen@alvherre.pgsql
to see if your changes would have any effect.  The inclusion graphs in
https://doxygen.postgresql.org may also be useful.
