Hi

what is sense of this function? There is not any comment.


What it does IIRC is complain about defined GUCs nobody registered an interest in. So you can say

EmitWarningsOnPlaceholders("bdr")

and any GUC with prefix "bdr." will result in an "unrecognized configuration parameter" warning in the log.
