No he didn't, just I've been sort of lurking on this subject ;-)
Actually, tar files are simply a small header, followed by the file's
contents. To add another file, you simply write another header, and contents
(which is why you can cat two tar files together and get a working file).

Which is why having them on stdout is still a nice option to have. You can
pipe the lot through your favourite compressor (gzip, bzip2 etc) and
straight on to tape, or whatever.
I don't know why you would want them as separate files - just think what
would happen to directory search times!!

Well, the custom format does that, it also does compression and can go t
If anyone can send me a nice interface for reading and writing a tar file

Hi
Could someone, please give me a little example on how to use listen/notify
mechanism. Or at least point me to some more legible documentation.
What I particulary need is that my frontend application is notified on

I think what's causing this is that you can't use zero as a Postgres

Is there a limit in PostgreSQL 7.0.2 on how many number of tables can be

Hello all.
I'm developer in Java with JDBC2.0.
How can I stora a binary (byte []) (such a certificate X.509,

Can I use the Type String (I think that not)?
Should I use LOB?

I had this same problem. Thanks to a suggestion from Bruce Momjian, I

I have a text file of SQL commands which contains tabs. I used to be able

and it treats the file as if I'm entering it all in manually. It treats
the tabs as completion commands.

If I understand correctly, you have something like this:
CREATE TABLE rec_* (
num integer primary key;
other ...
);
CREATE TABLE notes (
name CHAR(20),
numINTEGER,
note VARCHAR(200),
PRIMARY KEY(name, num)
);
So, you have many different tables like rec_*
