Based on the application usage trend, we're finding that we need to increase maximum number of concurrent connections to the database server, that is "max_connections" parameter. Of course, I also understand that it requires more system physical memory. My question is, what are all the PostgreSQL conf parameters that I must take into account/consider to adjust/modify, if we increase system physical memory and "max_connections"? Regards, Gnanam
