multiple freeradius instances with sqlippool, is it safe?

[Matteo Sgalaberni]

Hello, 

I'm would like to have multiple freeradius instances (processes on different servers) all pointing to the same postgres database. 
(My goal is to have a freeradius service redundant, I have a postgresql cluster with patroni/haproxy and each radius server point to all of them via a dsn multiple host connection definition and obviously it's connected to the master) 

I would like to use the sqlipool module. Is it safe use it in this scenario or does exists some side effects (I have some ideas of what could be wrong but I would like a your opinion...)? 

Do you have suggestions to what to pay attention to in this scenario? 

Thanks 

M.
