removeConnection() permanently removes a connection from the Load Balancer connection pool.
Connection numbers are currently determined by the order in which a connection is added to the connection pool. If the connection is successfully removed (the integer value provided refers to a valid connection), the return value is true, else false
$response = $db->removeConnection(2);
If the last remaining
readOnly connection is removed, the pool will revert to a normal ADOdb connection, with all commands being processed by the
write connection. However, if the
write connection is removed, then any attempt to use commands that modify the database will fail.
