Temporary file usage is sometimes attributed to the wrong query in the logs output. One identified reason is that unnamed portal cleanup (and consequently temp file logging) happens during the next BIND message as a, after debug_query_string has already been updated to the new query. Dropping an unnamed portal in the next BIND message is a rather old protocol behavior (fe19e56c57, also mentioned in the docs). log_temp_files is a bit newer than that, as ofbe8a431881. This commit adds tests to track which query is displayed next to the temporary file(s) removed when a portal is dropped, and in some cases if a query is displayed or not. We have not concluded how to improve the situation yet; these tests will at least help in checking what changes in the logs depending on the proposal discussed and how it affects the scenarios tracked by this new test.
