Hi
I have just released SHSQL under the GPL, it is a method how SQL can be
easily integrated into shell scripts.
The web site is at http://www.edlsystems.com/shsql and can be downloaded
from ftp://ftp.edlsystems.com/shsql
(Needless to say a PostgreSQL version is included)
Enjoy

Right. Single quotes tended to be an issue. Not so with 8.0. It's

I've been working with PostgreSQL on OS X (G4, G5 and dual G5 systems)
for a few months now, and overall I've been really pleased; for us, it
seems to be a good match.
If you have both an OS X and a Linux or BSD system available, you could
run pgbench against both and get a rough idea on how th

Hi. Thanks for responding.
I don't *think* there are circular references, but the nature of the
problem is that the code doesn't know anything about the semantics of
the schema - it just gets the list of tables, and there are multiple
schemas it needs to handle, all of which may change over time.
To the best of my knowledge, this is not possible in psql.
You can edit individual queries with \e, but I don't think it's
possible to edit functions.

My guess is that you will get better performance from a similarly priced
Dual Opteron for the following reasons:
1) OS-X is not 64-bit yet, 64-bit Linux/BSD OS's are available
2) GCC is far better tuned for x86 than PowerPC/Itanium/etc
3) Postgres *seems* to prefer Opteron's ondie memory controll
It seems like you would find it much easier to do this with a language
external to postgres (E.g., Perl) than relying on any of the built-in
languages and file I/O mechanisms.
Is there a reason you need postgres to handle this functionality?

Kari,
Why not select count(*) from the table and multiply it by a true 0.0 - 1.0
pseudo random number generator? Then adjust the outcome for the range of
uids. If the uids (or some other column) are contiguous starting at 0,
this would be a snap.

I am generally interested in a good solution for this. So far our
solution has been to increase the hardware to the point of allowing
800 connections to the DB.
I don't have the mod loaded for Apache, but we haven't had too many
problems there. The site is split pretty good between dynamic and

Hi,
Anybody know/have functions or package to create text
file from postgres function?
I want to execute a function to take some fields from
a table and save it in a text file (or xml format).
I need function like:
createfile(filename);
appendtofile(filename,text);
etc.
thanks
I'm a little late to the party, but figured I could at least offer some info for
the archives.
If you don't know the user's password, and you have admin access, then it really
doesn't matter. In fact, I set any special users (pgsql, mailman, etc.) up so
that they *cannot* be logged into normally.
Replying to myself..
Actually I found an answer. If a I wrap the split point selection to
subquery then the range of results is from 0 to maximum value (~120k in
this case)

No, and I'd vacuum full template
IIRC, this was discussed a few times on this list, searching the
archives might get you some results. AFAIR, the only way to do it
efficiently is to have a column specially assigned for this purpose, and
populate it with random numbers in a big range. The column should be
indexed to assure fast acc

How about

Hi!
I have to select a random row from a table where primary key isn't
continuous (some rows have been deleted). Postgres just seems to do
something strange with my method.
