Not exactly. SQL Analyzer also includes live monitoring of whatever queries
are coming into the database. You can achieve something similar by enabling
query logging in the settings.

I think a better approach is to handle configuration management with a
table in each schema. Update the schema, update the table. This works
well with automating database upgrades as well, where upgrades are written
as scripts, and applied in a given order to upgrade a database from release

If I'm understanding you correctly, you can do something like:

(select 'x'

where colc = colb)
from tablea
Since that has a subselect, you may get better performance with

Hi,
I'll try to switch from Oracle to postgres for some small applications.
Is it possible to build functions like Oracle's nvl or decode with

How can I make a function like nvl that works for every datatype?

Try coalesce. The syntax is the same as nvl.

I was recently running into performance problems with a query
containing now()::date or CURRENT_DATE. When I went to debug,
'now'::date made efficient use of the index (on a timestamp field).
The docs say that 'now' is turned into a constant right away. Is this
overhead/poor planning
If you don't mind spending a little money and are on Windows, you can

If you use a serial datatype, it simply says the *default* behavior is
to use the next value of sequence a. So you can insert 1, 2,
10,204,492 into the column just fine. However, by inserting data into
something you want to auto-increment, you can run into non-uniqueness.
(Like you were).
drop table A;
create table A (
id SERIAL PRIMARY KEY,
foo int default 5,
bar int default 10
);
insert into A (id, foo, bar) values (1, 1, 1);
insert into A (id, foo, bar) values (2, 2, 2);
insert into A (id, foo, bar) values (3, 3, 3);
insert into A (id, foo, bar)
