The method of initializing the repo via a map[string]**sqlx.NamedStmt usually works well, until you hit the case where two identical SQL statements should be registered somewhere (this probably happens more in tests than it does in real life, but it can plausibly happen). Making the initialization loop operate on an array of structures sidesteps this problem quite nicely: With this change, every SQL statement can get registered on a NamedStmt field, no matter what its shape or how similar it is to other statements on the repository.

It occurs to me that you could get the exact benefits of this change with the lining-up nature of key/value things in maps by just flipping the map type from |

As @nelhage and I discussed out-of-band earlier today, using a
map[string]**sqlx.NamedStmtworks well until you have to put two of the same SQL statement into the repository: Suddenly, one slot stops getting initialized. The change in this PR alters the initialization loop to use an array of structs, which eliminates the uniqueness requirement and should give us all some peace of mind (:Slight downside is that there's a little bit more line noise and that what was nicely lined-up key/value pairs before no longer lines up. But I believe the gain in correctness is worth it.
