Hello. I'am new. Please, sorry about my English. It's terrible!!! I try to obtain a fragmentated database with Postgres. I design a database structure, and really the fragmentation is ready. I have problems with data exportation/importation only. I has think really in many alternatives: dumps, and logs, auxiliar tables, auxiliar files...the problem is than I need save the INSERT, UPDATE AND DELETE commands...I need so so audit the database entries...for do the posterior data centralization. My database scheme supports the centralization, but I have problems with for audit database entries. When I think about a posibility, really I allways found a problem with that... If you have an idea about this, please tell me about that. Thanks you. Yessica.
