Thanks.
Is it on your todo list to something like this…? It is the opposite of "/* NO LOAD BALANCE */".
Make a "/* SLAVE */" type comment to force it to a slave? It would be helpful in forcing a query to a reporting server if you know your what your reporting queries are.
“Set weight_secondary to 0.”
Did you mean Set weight_master to 0. Unfortunately this would not help on a query by query basis, but the above would.

It's on my TODO but will not be a trivial change.

Pgpool will send any query not starting with "SELECT" or "select" to
the master. So you can insert a white space or a comment, for example
"/* NO LOAD BALANCE */" at the beginning of the line to prevent the
query to be sent to the slave.

Set weight_secondary to 0.
