pgroonga_standby_maintainer error

OS: FreeBSD
PostgreSQL Version: 11.21
PGroonga Version: 2.4.7
libgroonga Version: 13.0.7

Error "function pgroonga_wal_apply() does not exist" when using pgroonga_standby_maintainer module with CREATE EXTENSION pgroonga with schema specified · Issue #373 · pgroonga/pgroonga · GitHub

pgroonga_wal_apply() pgroonga_vacuum()を作成してエラー回避したが、以下問題でうまく動かない

(1)
すでにPgroonga WALがある状態でpgroonga_standby_maintainerを設定
Pgroonga WAL適用が完了するまでレプリケーションが止まる？待てばOK

(2) pgroonga_wal_applyでエラー
