Hi!
A quite impressive list of changes in version 8.0.0. ...
But the question from me is: When is it done?
We have a lot of 7.2.5 versions running which badly needs an update, but
if version 8.0.0 comes in the near future, we could surely hold out a
while longer and go for the top of the line.

The query have been running ok for some time now, but this morning I
decided to run vacuum analyze (vacuumdb -a -z) on the cluster, and
suddenly the query isn't running very well at all. This query has only
one value in the "IN", if I add another id the query becomes really
really slow.

What is "text + text" supposed to do right now? It doesn't seem very
useful to me. What about making "text + text" as an equivalent for "text
|| text"? Most strongly-typed programming languages do this. And MS SQL

Btw, MySQL manual used to recommend (or still does?) defining all
columns as NOT NULL as much as possible, "because NULL is slow"... :-)
For me it's pretty obvious, if you are never going to allow the column
to have an "unknown value", then define it NOT NULL to let the database
guarantee that.

Dear Postgresql people,
For the first time I'm trying to use pg_restore to do a partial restore.
It looks as if it should be easy: pg_restore -l, filter out the
required tables, then pg_restore -L. But unfortunately the listing
generated by pg_resotre doesn't include the schema name! Since m

How can a delete rows from a table that has foreign key constraints?
Here is how I have it set up.
I have 2 tables, tableA has fields and id's and tableB has fields that
reference tableA's id's. I'm not able to do this
BEGIN TRANSACTION;
DELETE FROM tableB
WHERE tableAid = 5;
DELETE FROM tableA
