There were some previous discussions (e.g. [1] and [2] more recently), but I don't think there was a real consensus on how to solve that problem. Storing a query text with fully qualified names (either the current query or a new field) is not practical for performance purpose, but there were no objections to storing additional information, like the active search_path when the entry was created. But as noted, while it technically gives the information you need it's far from being convenient to use, which is probably why it was never implemented.
