Description:

When starting a fresh ProxySQL instance, if the configuration file doesn’t specify pgsql-interfaces or mysql-interfaces, these values end up being empty in the global_variables table.

However, ProxySQL does load default values for these interfaces in runtime_global_variables.

Expected behavior:

ProxySQL should automatically set default values for pgsql-interfaces=0.0.0.0:6133 and mysql-interfaces=0.0.0.0:6033 in global_variables if they are not explicitly defined in the configuration file.
