Commit 08146775acd8bfe0fcc509c71857abb928697171 changed do_copy() to temporarily scribble on pset.cur_cmd_source. That was a mighty ugly bit of code in any case, but in particular it broke handleCopyIn's ability to tell whether it was reading from the current script source file (in which case pset.lineno should be incremented for each line of COPY data), or from someplace else (in which case it shouldn't). The former case still worked, the latter not so much. The visible effect was that line numbers reported for errors in a script file would be wrong if there were an earlier \copy that was reading anything other than inline-in-the-script-file data. To fix, introduce another pset field that holds the file do_copy wants the COPY code to use. This is a little bit ugly, but less so than passing the file down explicitly through several layers that aren't COPY-specific. Extracted from a larger patch by Kumar Rajeev Rastogi; that patch also changes printing of COPY command tags, which is not a bug fix and shouldn't get back-patched. This particular idea was from a suggestion by Amit Khandekar, if I'm reading the thread correctly. Back-patch to 9.2 where the faulty code was introduced.
