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.
