Placeholder abstraction for DB drivers (eg, Postgres)

[cbusbey]

See #283. We may want to consider adding something like sqlx or better, implement a driver type abstraction to handle driver specific placeholders.

So there is currently no workaround for this? pq throws an error for me when trying to setup the sqlstore.

The fork from alpacahq solves this issue. It'll be awesome if this gets merged upstream. Makes a lot of sense too based on #283

Appreciate you mentioning this @shadiakiki1986, we have been using the fork with great success.

Hi @cbusbey,

Do you know if there are plans to merge #404 ?

If not, and if something else would be required to be merged, what should this solution look like in order to be approved? I plan to use quickfixgo with postgres and could help implementing something, but I would prefer avoiding the overhead of maintaining a fork...

Thank you!

[cbusbey]

merged! sorry for the delay on that
