Re: bugfix: incomplete implementation of errhidecontext

The following review has been posted through the commitfest application:
make installcheck-world:  tested, passed
Implements feature:       tested, passed
Spec compliant:           tested, passed
Documentation:            tested, passed

This is trivial bug fix in the area of hiding error context.

I observed that there are two places from which we are calling this function
to hide the context in log messages. Those were broken.

This patch fixes those.

So good to go in.

The new status of this patch is: Ready for Committer
