+- the connection pool uses a "threadlocal" strategy internally to return
+ the same connection already bound to a thread, for "contextual" connections;
+ these are the connections used when you do a "connectionless" execution
+ like insert().execute(). This is like a "partial" version of the
+ "threadlocal" engine strategy but without the thread-local transaction part
+ of it. We're hoping it reduces connection pool overhead as well as
+ database usage. However, if it proves to impact stability in a negative way,
+ we'll roll it right back.
- Fix to bind param processing such that "False" values (like blank strings)
still get processed/encoded.
