I am going to write an application tht writes big amounts of plain text
into a database.
What kind of data are those? Articles? News/mail messages? Other?
I thought of using the text type for this, but I don't know if it has a
maxlenght, and given that these will be very long texts I

Could u just tell me if it is possible to have a Windows Client and the

something like the ODBC.
Yes, although it's preferable to use a native library.
Does Postgres have anything for the advanced features like OleDB
I'm partial to the ZEOS Database Explorer myself. I don't have experience
with a multitude of tools, so the best I can offer is that I have no
problems with the latest version :) Actually, I can tell you that it has the
advantage of a native interface (rather than relying on ODBC). And it's

When the name of a sequence auto-generated from a SERIAL type would be
longer than 32 chars, it appears that CREATE TABLE uses a different
name truncation algorithm than DROP SEQUENCE. Example below. Note
the difference between the following:

How do these operate on each other, do I also use parentheses?
Yes, if you don't want to think hard about what the precedence is

Kinda hard to believe.
I know it, but that's what I am seeing. (to recap, my trigger only
fires on the first insert per connection.)
This will be kind of long, it's a spliced-together version of my psql
client session and the server log. I drop and re-create the procedure
and trigger,
I rebuilt with these changes and am seeing a 30-40% improvement in average performance
for
my high-contention high-volume copy case. I still need to do some more testing, but
this really
seems to help.
Thanks a lot Tom!

Earlier I posted with my problems about the WAL logs eating up all my
