Yeah. The log_connection data that you already have is pretty much
everything that Postgres knows about where this problem is coming from,
because the session terminates as soon as this error is discovered.

I'm jumping to a conclusion here, but: I'm suspicious that the cause is
a malformed JDBC-style connection URL, made by some program that thinks
a schema name could be part of the URL. (Perhaps there are other DBMSes
where it actually can be done that way.)
