may be called against a stale connection without the "connect"
event handler having been called, in the case where the pool

an AttributeError against NoneType would be raised instead.

un-adjusted internal symbol names for "anonymous" labels, which
are the "foo_1" types of labels we see generated for SQL functions
without labels and similar.  This was a side effect of the
performance enhancements implemented as part of references #918.
