This is simply an attempt to have https://github.com/jmoiron/sqlx and https://github.com/jackc/pgx interop together directly, rather then through pgx/stdlib. Unfortunately some of sqlx needs to be reimplemented in order to achieve this, but ideally this will be kept to a minimum.
sqlx and pgx are both great libraries, and having some of the sqlx functionality work directly with pgx makes using pgx specific funtionality simpler/possible, as well as leading to improved performance (hopefully?)
Whenever I reimplement (read: pretty much copy paste) sqlx functionality in this library, I make a point of commenting a link to the the exact line and commit in Github the code block is coming from. This is mostly caused by certain struct attributes / functions being private to the sqlx package. If they are ever made public, or have some way to publicly interop with them, these reimplementations won't be necessary.
Any function suffixed with x represents functionality achieved through sqlx, OR new functionality implemented in this library. Any function suffixed with xx represents a function in pgx that is also suffixed with x
VERY much a work in progress.
BIG THANKS to the authors of both pgx (https://github.com/jackc) and sqlx (https://github.com/jmoiron). This would not be possible without them.
