e database itself
will detect the corruption and not even hand the data to
psycopg2.
IMHO a driver should not hand over to the client any bad data
unless explicitely told to do so, which latter case does not
seem to be covered by the DB-API specs, regardless of what
the majority of drivers might d
be at fault now.
The one thing that did change is PostgreSQL going from 9.6 to
10, effecting a libpq5 recompiled against the newer PG
client. I wonder whether psycopg2 needs a recompile against
that libpq5 (despite there not having been changes advertised
by PG).
I guess I'll have to downgrade libpq5 to 9.6 and see what
happens.
I'll report what I find.

Dieter, thanks for taking the time to explain the general
procedure. However, recompiling a library and trying to find
out where given block of memory comes from is way beyond
skills. I fear
le it doesn't return True (as I mistakenly
suggested) it does return False, always, which is the very
same reason for OP's problem, namely returning a string,
doing a logic test on that, and assuming that would tell
whether the check succeeded or failed.
Unless I am totally mistaken :-)

Surely, but it can make reusing code a nightmare.

In that situation, is it preferable to choose a nonsensical
name over a mediocre one ?

On the other hand, Japanese is full of wondrous word-play at

ensical name might lead readers to
go beyond the name when trying to understand code, and would
prompt me to improve upon the name upon reading my own code (and
having acquired, likely, a better understanding of the concept
that's to be named).

Mailing lists don't subdivide by topic.
Your mailer may allow you to filter by Subject:.

not applicable
The equivalent would be the Subject: header.

Do we _know_ it's a lie ?

I just might so happen that the homework assignment did not
contain much more in terms of description.

One CAN NOT.
The best you can do is to go ask the canonical source of the
file what encoding the file is _supposed_ to be in.
Then go from there and allow for errors.

That doesn't solve the "next to" part in

Sure, but notice how I said "(easily)" in the original answer ?
The above is NOT easy for an OP who has to ask the original question.

Agreed.
Note that I had a lurking suspicion this whole thing amounts
to a homework assignment (which I didn't say, however) ... ;-)

The quick fix:
put an r in front of the direc

For that you'll have to read up on strings and escaping.

The answer lies in the (inadvertant) use of escaping.
Which is the very reason _why_ forward slashes were favoured
over backward ones.
