I'm pretty sure that's the expected behavior of a connection pool. It
opens a bunch of connections, does some initialization on them (which
likely includes the "SET extra_float_digits = 3" bit) and then keeps them
around so that the application can use them.
You have not really explained how it's killing your application, though.
My guess is it's either not going through the connection pool (and so is
hitting max_connections or something) or it's misconfigured in some other
way. In any case, extra_float_digits is not the root cause here.
