Interesting. I think you're right. Looking at the Wireshark traffic
again, the driver seems to issue a portal-variant Describe when using
unnamed prepared statements, but as soon as the named prepared
statements kick in (per prepare threshold), the Describe is a
statement-variant Describe with the expected behavior you've noted.
Actually, the driver sends Parse / Bind / Describe with the unnamed
statement, but for some reason switches to Parse / Describe / Bind
with named ones.
