[Cl-perec-devel] Troubles with cl-perec

Hello,

I'm playing with cl-perec and cl-rdbms whose feature sets are
impressive, but that unfortunately aren't working for me. I'm using
PostgreSQL 8.2.5 from Darwin Ports and SBCL 1.0.12.15 (ppc). I'm
pretty sure I have the latest stuff of everything (including the
branches from cl-dwim) and I have wiped out all my fasls and started
anew. So here's a small test case, taken from cl-perec website:

CL-USER> (asdf:oos 'asdf:load-op :cl-perec)
[...]
NIL
CL-USER> (asdf:oos 'asdf:load-op :cl-rdbms.postmodern)
[...]
NIL
CL-USER> (asdf:oos 'asdf:load-op :cl-perec-test)
[...]
NIL
PRCT> (setq *database*
            (make-instance 'rdbms:postgresql-postmodern
:connection-specification
                     '(:database "rs" :user-name "rs" :password "rs")))
#<POSTGRESQL-POSTMODERN {118AB229}>
PRCT> (start-sql-recording)
; No value
PRCT> (defpclass c1 ()
        ((s1 :type string :initform "no" :initarg :s1 :accessor s1-of)))
#<PERSISTENT-CLASS C1>
PRCT> (with-transaction
        (make-instance 'c1 :s1 "hello"))
; BEGIN
; SELECT relname FROM pg_class WHERE relkind = 'r'
; CREATE TABLE _c1 (_id BIGINT NOT NULL PRIMARY KEY, _s1 TEXT)
WARNING:
   Postgres warning: CREATE TABLE / PRIMARY KEY will create implicit
index "_c1_pkey" for table "_c1"
; COMMIT
; BEGIN
; SELECT relname FROM pg_class WHERE relkind = 'S'
; CREATE SEQUENCE _instance_id
; SELECT NEXTVAL('_instance_id')

Somewhere around here, I get this error:

There is no applicable method for the generic function
  #<STANDARD-GENERIC-FUNCTION CL-PEREC::CREATED-INSTANCES-OF (1)>
when called with arguments
  (#<#<STANDARD-CLASS NIL {146769C1}> :begin-executed-p #t {14663BF9}>).
   [Condition of type SIMPLE-ERROR]

; COMMIT
NIL
T
PRCT>

Also, in this case I commited the transaction, had I not the
_instance_id sequence wouldn't have been created but
prc::*oid-instance-id-sequence-exists* would get set to T anyway and
then I would get errors about _instance_id not existing.

Any ideas?
