How to rotate DB credentials elegantly with gino?

[MarkBrook]

Hi!
There is an approach with creator parameter in SQLAlchemy create_engine to replace a connection and this way we can check if there are still valid connection credentials and reconnect if not. Is there any way to do this in GINO?

The only way I tried is by inheriting a asyncpg.Pool object like this:

class AnotherPool(Pool):
    async def acquire(self, *, timeout=None):
        try:
            return await super().acquire(timeout=timeout)
        except NotValidCredsError:
            self._url = get_new_connection_url()
            await self._init()
            return await super().acquire(timeout=timeout)

Hacky and not so good solutions with possible errors.
