Maybe this is Npgsql removing connections from pool after some time.
But it may not be this case because Npgsql finishes the connection
correctly when removing it from the pool.
You can confirm that by playing with your max connection pool and min
connection pool values in your connection string. Try to put a higher
value of min connection pool, so they aren't closed too frequently.
Also, as Richard said, check your connection usage pattern in your application.
I hope it helps.
