Hi.
https://www.pgconfig.org/#/?max_connections=300&pg_version=16&environment_name=Mixed&total_ram=16&cpus=2&drive_type=SSD&arch=x86-64&os_type=linux gives me the following output with both the API and through the website -> Export Config.
Memory Configuration
shared_buffers = 0
effective_cache_size = 0
work_mem = 0
maintenance_work_mem = 0
It should be
Memory Configuration
shared_buffers = 2GB
effective_cache_size = 6GB
work_mem = 5MB
maintenance_work_mem = 410MB
