That's probably how the "FreeBSD" reference got in there: somebody saw "Berkeley" and decided "FreeBSD" would look more "techie". It's stupid, but nothng to excoriate the reporter about. Sometime back we were announcing a product and practically wrote everything for the journalists and gave it to them so that they could just print it, and one newspaper still got LOTs of things wrong. In contrast another newspaper was much better tho - facts right. The standards haven't changed much, so I don't really bother reading the first newspaper for a lot of things. Whereas the 2nd one still seems to do ok for tech stuff. They're very rarely 100% correct.

[HACKERS] integer arrays
I have looked and I have looked, it is not immediately clear to me how integer
arrays are passed to C function.
create table fubar (vars integer[]) ;
select c_function(vars) from fubar;
insert into fubar (vars) values ('{1,2,3,4,5,6}');
extern "C" c_function (varlena var)
{
int * pn = (int *)VARDATA(var);
}
Now, what should "pn" have in it? I don't see my values until later on in the
array. I guess I am asking is what is the format of this type, and more
importantly, where is it documented. I looked in catalog and pg_types but it
wasn't clear it was defined there.

RE: [HACKERS] Truncation of object names
The ability to place database objects into a logical partitioning of data. For example, in Oracle, each user creates tables, views, sequences, synonyms, and snapshots in their own schema. So if I were to create a table called 'Employees', I could query it as: SELECT * FROM employees; But another user would have to query it as: SELECT * FROM mascarm.employees; A common case for this is to logically divide schema by departments. You could do that now in PostgreSQL in the form of multiple databases, but you couldn't query across them. For example, you might have an "Accounting" schema, and an "Inventory" schema. Occassionally, the accountants need to join tables from accounting w/inventory. The inventory people (or the dba) would then grant appropriate privileges for the accountants to do that, but the accounts would have to fully qualify their queries: SELECT * FROM inventory.orders; So, if you want a logical division that also contain some shared tables, views, or sequences (and hopefully snapshots, some day), in Oracle, you can create public synonyms for the shared objects: CREATE PUBLIC SYNONYM employees FOR mascarm.employees; Now, anyone can query this table as: SELECT * FROM employees; Its a namespace thing, basically.

[HACKERS] JDBC Select Performance
Hi, While doing some testing with Postgresql 7.1, I noticed some perculiar behaviour with the JDBC driver. Selecting a single record from a table is 5-10 times slower than doing an insert (even if the table only contains a single record, and the select query does not contain any join). On Oracle database, an insert is always slower than a select when running the same test. At the moment, I've narrowed down the time consuming section of the code to ExecSQL() method in the org.postgresql.Connection class. There seems to be a "while" loop over a "switch" statement which I yet need to figure out what it is doing. Anybody has any idea why this section of code is so slow? Note: I'm using Mandrake 7.2, IBM JDK 1.3 on 1Ghz Athlon with 256 RAM. The Postgresql 7.1 is compiled with multibyte character turned on. The Select statement itself takes 1-5 seconds which is almost 100 times slower than Oracle on the same PC. This is even without opening connection factored in.
