Query returns error "there is no parameter $1" but server logs that there are two parameters supplied

Hello,

PostgreSQL slack suggested I submit this as a bug report as we are supplying parameters but the server is saying we're missing 1. Even when we supply 2 or more to our queries.

The following is the server logs & parameters supplied for a query that returns an error message. This occurs around 2-10 times per hour on a database with around 120-1000 queries per second. With around 300 users connected, with roughly two thirds of those users idling due to connection pools in the application code (node-pg).

We have other queries logging the same error on a different database on the same server infrastructure using golang based connection pools/drivers (jackc/pgx).
