How How to correctly connect the Postgrees database in Digital Ocean via pool?

I use the same Postgrees database for development and production. Whether correctly I understand that use of connection through pool should provide the best productivity? I tried to connect access to the pool in Wappler, but then the base scheme disappears. Perhaps this should be done somehow in parallel with the main connection?
