I need to create some nearly identical copies of rows in a complicated
table.
Is there a handy syntax that would let me copy a existing row, but get a
new primary key for the copy? I'd then go in an edit the 1 or 2
additional columns that differ. The duplicate would be in the same
table as the
Is it possible to issue an SQL query that lists column names, types (int,
varchar, boolean, etc.), properties (like NOT NULL or UNIQUE)
for a given table name ?
Start psql with the -E option. Then "\d yourtable". It will print out
the queries that are run internally to show you the table info
At least I think that would do it.

I want to update a column in myTable. The value this column is set to depends
on a
nested select statement which sometimes returns 0 rows instead of 1. This is a
problem since the column I'm trying to update is set to refuse nulls. Here's a
sample:
update myTable set myColumn = (Select altColum

You might look at how some of those C code indenter's work. Seems like

This worked for us in 7.something (don't need it anymore, but it should
still work).
You'll want to create one for INT8, INT2, etc.. if you are going to use
those as well...

Not that this is the best solution, but I read in a book (SQL for smarties
I think) the following (maybe I'm wrong, but this is what I remember :)

Just drop the table using "DROP TABLE mytable;" and ignore the error...
I'm sure there are fancy ways of doing it by accessing system tables, but
the above works for me.

In 7.1 it's there... using the |(or) &(and), etc.. operators. In 7.0.3
it's not although can be added easily.
example:

Take a look at the SERIAL datatype as well as sequences (CREATE SEQUENCE,
NEXTVAL, CURRVAL).
good luck!

There's probably a way to get that serial number.
I think I remember reading that when you specify it as SERIAL,
postgresql actually creates a separate sequence. If that's the case
then you could do "SELECT currval('mysequence')" -- although I'm not
sure what "mysequence" should be set to.
