Can you show a test case in which this happens? I added some
instrumentation and verified at least within our regression tests,
copy_plpgsql_datums' CurrentMemoryContext is always plpgsql's
"SPI Proc" context, so I do not see how there can be a query-lifespan
leak there, nor how your 0003 would fix it if there is.
