Nothing in namespace.h seems to be of any possible use for frontend
code. If there were possible use-cases I'd be inclined to agree, but you
obvoiusly can't use any of the functions, the structs and the guc make
no sense either. So I really don't why we should cater for that?
I think the likelihood of actually breaking correct working extension
code that uses namespace.h that'd be broken if we removed lock.h from
namespace.h is an order of magnitude bigger than the possible impact on
frontend code.
