Well we've learned that when you have lets say five tables which all contain name, adresse, city and so on you also have a form of redundancy... Can be wrong, though ;o) When dealing with relational databases, that redundancy (or the process of eliminating it) is called normalization. This usually involves breaking tables apart into smaller tables. There are several 'normal forms' which database designers strive for... each normal form is closer to the 'ideal' database, although most designers don't bother with much beyond 3rd normal form. Of course, it can be wise to break the rules for performance reasons... Anyway, I highly recommend reading up on the topic...

[GENERAL] Two tables for the price of one?
I am seeing something kinda weird when I am creating tables (or viewing existing ones): BEGIN SESSION bash$ createdb test CREATE DATABASE bash$ psql test Welcome to psql, the PostgreSQL interactive terminal. Type: \copyright for distribution terms \h for help with SQL commands \? for help on internal slash commands \g or terminate with semicolon to execute query \q to quit test=# \dt No relations found. test=# CREATE TABLE mytable ( test(# id INT, test(# stuff VARCHAR(10) test(# ); CREATE test=# \dt List of relations Name | Type | Owner -+---+-- mytable | table | gmguest mytable | table | postgres (2 rows) test=# /END SESSION As you can see when I create a table it appears it is either creating it twice (not likely) or thinks that there are two instances of it. The gmguest user is a guest user for another database however any database I look at has another table for each table with this gmguest user as the owner. I found this after seeing duplicate table names while trying to access a database via odbc and MSAccess. Anyone seen this before? I imagine somewhere I screwed up a system table or something (don't remember doing it). I may just recompile and dump and resoter the tables from scratch but I'd like to avoid it if possible.

[GENERAL] C functions, arguments, and ssh oh my!
Hello All,
I am writing my first C function for postgres and failing miserably. my C
function needs to get passed a username (char) , uid(int), and gid(int) and
what it does with those is builds a command string for an external app that
is called with system() and exits 0. I know this is strange and ugly but I
need to trigger this external app when an insert is made into a user table.
I am looking into the version 1 calling convention to get these arguments
into my C function but I can't seem to match the types correctly. I am
looking at SPI with triggers now but I don't know if that will work either.
Am I barking up the wrong tree here? any comments are appreciated and I
appreciate the time you have taken to read my post. Below is to cludgy poor
code I have so far (it doesnt work of course) and I am halfway between
converting to version 1 calling but I wanted to give you an idea of what I
am trying to do. Thanks again.

You missed the part about fetching the arguments using PG_GETARG_xxx.
Also you should use PG_RETURN_xxx and you need to null-terminate your

If the transaction doing the insert is later rolled back, the insert effectively never happened --- but the effects of your external app will still be there. I'd suggest thinking twice about your whole system design, if it requires this. You can mitigate the problem a little bit by making the trigger an AFTER trigger, so that it's only fired when we are about to commit the transaction. But there's still a possibility of trouble if a later AFTER trigger decides to abort. regards, tom lane ---(end of broadcast)--- TIP 2: you can get off all lists at once with the unregister command (send "unregister YourEmailAddressHere" to [EMAIL PROTECTED])

[GENERAL] fmgr, C , and character arguments
Hello all,
I am having a bit of trouble getting my arguments formatted into a
command string for system(). Here is what I have so far for code.
#include string.h
#include stdlib.h
#include "postgres.h"
#include "fmgr.h"
PG_FUNCTION_INFO_V1(ssh_exec);
Datum
ssh_exec(PG_FUNCTION_ARGS)
{
char*uname = PG_GETARG_CHAR(0);
char*uid = PG_GETARG_CHAR(1);
char*gid = PG_GETARG_CHAR(2);
strncpy(sshcmd, "/usr/local/bin/plsshexec ", 255);
strncat(sshcmd, *uname, 255);
strncat(sshcmd, " ", 255);

strncat(sshcmd, " ", 255);
strncat(sshcmd, *gid, 255);
system(sshcmd);
return 0;
}
I am thinking that strncpy is not a bad idea after moving to the V-1
function manager interface. As I am sure you can see I am a C hack at best.
what is the best way to format the string and make this code work? memcpy?
