That's very bizarre, and I don't recall any similar reports in the
recent past.
Server is PostgreSQL 15.7 (Ubuntu 15.7-1.pgdg22.04+1)
I haven't been able to find out what client version they are using yet,
but I suspect it's quite old.
It would definitely be interesting to find out what the client-side
code is, including the openssl version being used.
They have psqlODBC 9.3 and 13.2 on a 64-bit Windows platform (probably
Windows 10). The problem occurs with both. I tried to replicate it with
psqlODBC 13.0 and couldn't.
Just to be clear that is 9.03 and 13.02.
OpenSSL is bundled with psqlODBC, AFAICS. For 13.0 that would be 1.1.1.8
(hmm, that doesn't look like an OpenSSL version. Would that be 1.1.1h in
Linux terms?). But the fact that it happens with two very different
versions but I can't replicate it with one in between (and quite close
The only thing I could find that relates to SSL directly in the move
from 13.00 --> 13.02 is:

Which happened at 13.01.
to one of them) makes it unlikely (IMHO) to be just version related.
There must be something else going on. I've asked them (their IT
department, not the user) to try to disable any anti-virus software.
That's a bit of a reach, but always a possibility if something behaves
weirdly on Windows.
