[Zope] Psycopg export/import

[William Herring]

As part of an object, I have exported several zsql methods from Zope 2.2.2
and imported to Zope 2.6.2.  In the later version I am using Psycopg as a
database connection to Postgres.  It is working fine for all ZSQL methods I
have created within 2.6.2.

However, the methods I imported from Zope 2.2.2 do not connect to the
database.  Message is "Warning: The database connection for this method
cannot be found!".  However, the Connection ID is shown and all appears to
be in place.

An ideas?  Thanks in advance.
