PG 18: pg_wait_sampling.so: undefined symbol: pqsignal

[lysalexy]

OS: RHEL7
DB: PostgreSQL 18(собрана из исходников c make install-world)

Успешно скомпилировались исходные файлы расширения
make USE_PGXS=1
make USE_PGXS=1 install

Появился .so файл.

Однако при попытке перезагрузки сервера БД с добавленнным postgresql.conf "shared_preload_libraries = 'pg_wait_sampling' " появляется ошибка.
