- Around line 145-146: Update the validation logic in
server/internal/api/apiv1/validate.go at lines 145-146 and 312 so database- and
node-level postgresql_conf overrides for hba_file and ident_file are rejected
when they reference non-default paths, unless the implementation also explicitly
validates and manages those referenced files. Ensure both validation sites apply
the same rule and prevent silently ignored pg_hba_conf or pg_ident_conf entries.
