Hi,
Our application receives a high load of requests per minute, about 100k/min. We noticed that our memory steadily grown. Doing the memory profiling, we notice a high in-use memory size in the following piece of code inside pq/conn.go in method DialOpen():

So, the doubt is: there is a limit to this grown (is it normal?) or we can consider a memory leak?
We didn't observe a decrease in the size of this buffer.

• go version go1.7.6 linux/amd64
• lib/pq version - commit: dd1fe20 (master)

Thank you for your attention.
