I have no conclusive proof for abuse, but a library has no business in "pgsql_tmp".
That looks very much like somebody guessed your superuser password and is hijacking
the operating system account.But he didn't say they were in pgsql_tmp, just that they were in some temp directory apparently 3 or 4 levels higher in the directory tree than where I would expect pgsql_tmp to be. To me this looks like some cruft left over from some sysadmin running the python package manager, perhaps while logged in as the wrong user. (Although I suppose that running a package manager as the wrong user is also something a hacker might try to do...)Cheers,Jeff
