ecpg: Fix NULL pointer dereference during connection lookup
ECPGconnect() caches established connections to the server, supporting
the case of a NULL connection name when a database name is not specified
by its caller.
A follow-up call to ECPGget_PGconn() to get an established connection
from the cached set with a non-NULL name could cause a NULL pointer
dereference if a NULL connection was listed in the cache and checked for
a match. At least two connections are necessary to reproduce the issue:
one with a NULL name and one with a non-NULL name.
