Hmm. Do you have any way to replace the non-core calls with something
else? The "shexec('rm -f ' || _OutputFile)" bits could presumably be
converted to use contrib/adminpack's pg_file_unlink(), or an equivalent
one-liner in plperlu or plpythonu. I don't know what the sqshf
incantation does, though.
This wouldn't be about fixing it so much as narrowing down where the
problem is.
