Subject Re: PK problem with Postgre
Date Thu, 20 Apr 2006 21:58:32 GMT
Surprise to me.  I use Postgres frequently and didn't run into any
problems or custom sequences.  I often switch between Oracle and
Postgres without changing the default PK generation.  My Postgres
sequences are routine, created like so:

create sequence pk_tablename
  INCREMENT 20 MINVALUE 1 START 200 CACHE 1;

Why do the Postgres developers suspect Cayenne?
