Even though ``0`` is documented as the max pool size in the aiopg docs, setting it to 0 causes an exception in `aiopg.pool.Pool._fill_free_pool`:
```
File "/Users/gavinr/Source/PSE/anabroker/env/lib/python3.7/site-packages/aiopg/pool.py", line 208, in _fill_free_pool
if override_min and self.size < self.maxsize:
TypeError: '<' not supported between instances of 'int' and 'NoneType'
```
Set to the same default as aiopg, @ 10.
