Hi,
... I have considered lots of things - but I didn't write the scripts!
Now that you mention it, I do remember that truncate is much better
than
delete from mytable;
That is not what they wrote but hey. But even then, what are the
advantages/disadvantages of temp tables? Is there a document somewhere
I can consult which will give me the lowdown on permanent (but
temporary) versus temporary tables in pg?
Cheers
