On reconfigure, we no longer passed a port for the extension server which caused us to not write out the neon.extension_server_port line. Thus, Postgres thought we were setting the port to the default value of 0. PGC_POSTMASTER GUCs cannot be set at runtime, which causes the following log messages:

LOG: parameter "neon.extension_server_port" cannot be changed without restarting the server
LOG: configuration file "/var/db/postgres/compute/pgdata/postgresql.conf" contains errors; unaffected changes were applied

Fixes: #9945
