Hi there,

I think that this may be my first post to this list so be gentle.

I'm having a very strange problem (to me) and I hope that someone can
shed some light on what I'm not seeing.

I created a database and table from the command line using: sudo su
postgres createdb test

That worked fine and created the stated table.

I then logged in using: sudo su postgres psql test

Again, that worked fine.

I created a table from the prompt using: create table users (userID
serial, userName varchar(32), firstName varchar(32), lastName
varchar(64), email varchar(128));

The table was successfully created.  So good so far.  Don't mind the
values of the varchar's; this is purely for testing.

I then added a primary key to the table using:  alter table users add
primary key (userId);

Again, it worked.

Here's where it starts to get weird.

I inserted data into the table using: insert into users (username,
firstName, lastName, email) values ('bfitzsimmons', 'Brant',
'Fitzsimmons', 'brant(at)bfcomputerconsulting(dot)com');

It went in properly and I was able to select the inserted data without
any problems (select * from users;).

I then wrote a python script to insert and select data from the
table.  The script is able to insert and retrieve data without any
problems...*but*...from the console I can't retrieve any of the
records inserted by the script.

Records that are entered at the console show up when I do a select
with the script, but not the other way around.  I have tried to the
RTFM as much as possible, but I'm still lost as to why while accessing
the same table I can't access the data manipulated by the script.  I
don't know if it has anything to do with tablespaces or what, but I'm
really starting to get frustrated.

I'm from a MySQL background and I'm completely stumped as to how you
can, through a script, insert data into a database *created at the
console* and not be able to select that data from the console.  I know
it's there taking up space on my machine, and I can select it from the
script, but I can't manipulate it in any way outside of that.

Any thoughts?
