Hello,
could you be so kind to help me with following requests ?
I need the maximum size of the following types : varchar(n) numeric(n,p) text bytea
Could you please give me the name of articles or publications and where I can find it for these requests ?
Well, the manuals would be a good source of information for this. Go to the website, and click "Documentation". There is a list of manuals on the right-hand side. A good place to start is
http://www.postgresql.org/docs/8.0/static/datatype.html
I want to transfer a oracle database 8i to postgreSQL 7.3.2. Is there an article or publication which related about this ?
http://techdocs.postgresql.org/ is a good place to start. Also, check the mailing list archives for specific points.
Oh, there is a French-language community site too at:
http://www.postgresqlfr.org/
One of their news stories concerns a company moving from Oracle to PostgreSQL too.
