Обсуждение: PG 9 adminstrations

Hi all,

I am trying to update / refresh one table (history) only from prod. database to my test environment database

my query as follows:

pg_dump -h <hostname1> -U postgres -t history DATABASENAME | psql -h hostname2 -U postgres -t history DATABASENAME > db.sql

but I am getting the following error

psql: FATAL:  database "history" does not exist

Can you help please?

what would be the script if I want more than one table (3 tables to refresh)

Kind regards

You don't need "-t history" on the psql part.  It doesn't do what you think it does, and it's reading the next part ("history") as the database name.

try:

pg_dump -h <hostname1> -U postgres -t history DATABASENAME | psql -h hostname2 -U postgres DATABASENAME > db.sql

Clearly the history table already exists on your second host. This may
or may not matter, if the table definitions are the same. If the table
on host2 was empty, it'll be filled with the data from host1. If not,
you'll need to truncate the table on host2 first. If you don't want the
complaints about tables or indexes or constraints that already exist,
use the -a option for data-only dumps.

Also, might I suggest using the pgsql-novice list? They're more likely
to help with general issues like this.
