specification 1.0.0, but not all cases are fully implemented
(particularly around bind parameters and prepared statements).

Bind Parameters and Prepared Statements
---------------------------------------

The PostgreSQL driver only supports executing prepared statements with
parameters that do not return result sets (basically, an INSERT with
parameters). Queries that return result sets are difficult with prepared
statements because the driver is built around using COPY for best
performance, which is not supported in this context.

**Beta** drivers are (mostly) feature-complete but have only been available for a short time.
**Stable** drivers are feature-complete (as much as possible for the underlying database) and have been available/tested for a while.
