Hi,
I am trying to use psql \set and \echo commands to set some internal
variables.
My variable starts with single quote and ends with single quote.
That is actual value of the variable.
Eg.
set cur_db 'pgdb'
\echo :cur_db
--I am expecting here 'pgdb' but psql shows pgdb
As mentioned above, I
Hello
\set removes outer quotes
if you use PostgreSQL 9.0 you can use

I need your advice.
My problem is to ensure that the right returning from insert on the view.
For example, I have two tables:
CREATE TABLE country (id serial, nm text);
CREATE TABLE city (id serial, country_id integer, nm text);
And one view on table city, which join table county and

That's useful to know -- thanks. At least now I know my idea won't
work, so I can forget about it
I have an instance of what looks like a weird mixup of data returned by the
server.
This is observed in a Java application using the 9.0-801.jdbc4 JDBC driver
connecting to an 8.3.4 server (yes, it's old) running on Solaris.
The application hung waiting for the result of one

Great eyes!
It was copied pasted out of some running notes screenshots of the

it was :) Thanks so much for taking the time to look at this.
Now, on to the next hurdle - getting pg_ctl to run as an automated service...

Rules are macros, and have the usual issues with multiple evaluations of
multiply-referenced arguments.

I think this is the syntax you want:

Anyone knows if I can use column aliases in having condition?
Something like this.

I have a table with a little active data and a lot of historical data.
I'd like to be able to access the active data very quickly - quicker
than an index. Here are the details:
1. Table has about 1 million records
2. Has a column active_date - on a given date, only about 1% are
active.
