Hi, I am not sure why, but I can't find "basic_archive.archive_directory" in pg_settings the same way I would find for example : "pg_stat_statements.max".
[local]:5656 benoit@postgres=# SELECT count(*) FROM pg_settings WHERE name = 'basic_archive.archive_directory'; count ------- 0 (1 row) show can find it if I use the complete name but tab completion can't find the guc: [local]:5656 benoit@postgres=# show basic_archive.archive_directory; basic_archive.archive_directory --------------------------------- /home/benoit/tmp/tmp/archives (1 row) The archiver is configured with "basic_archive" and is working fine. I use this version of pg: PostgreSQL 15beta2 on x86_64-pc-linux-gnu, compiled by gcc (GCC) 11.3.1 20220421 (Red Hat 11.3.1-2), 64-bit
