Hi all,
The undocumented GUC called xloginsert_slots has been introduced by
commit 9a20a9b. It is mentioned by the commit that this parameter
should be removed before the release. Wouldn't it be a good time to
remove this parameter soon? I imagine that removing it before the beta
would make sense so now is perhaps too early... Either way, attached
is a patch doing so...
Regards,
