Environment

postgres=# select * from pg_extension;
extname | extowner | extnamespace | extrelocatable | extversion | extconfig | extcondition
--------------------+----------+--------------+----------------+------------+---------------+--------------
plpgsql | 10 | 11 | f | 1.0 | |

pgaudit | 10 | 2200 | t | 1.2 | |

The above alarm occurred during the compilation process, because of the above alarm, we were worried that this extended function would not run stably on the production system.Please help analyze this problem. Thank you very much
