PostgreSQL, often simply Postgres, is an object-relational database management system (ORDBMS) available for many platforms including Linux, FreeBSD, Solaris, Microsoft Windows and Mac OS X. It is released under the PostgreSQL License, which is an MIT-style license, and is thus free and open source software.
I'm currently running Fedora 17 and am considering running Postgresql as a database server. In looking over the install of postgres I notice that it is installed in /var/lib and the database data is kept there also. Why is the postgres user and the database data not kept somewhere that is not so intergrated into the OS.
I need to take a Microsoft SQL Server database backup (dump) file and import/restore into a PostgreSQL database. Does anybody have some sort of transform script (maybe a perl/sed/awk script) that could be run on the MSSQL Server backup file, so that it could be restored to the PostgreSQL database? Let's assume the tables have already been created in postgres, but they are all empty.
TO make a database backup in postgreslq server you use pg_dump and psql commands.
First, locate the database:
# psql -l --username postgres --password
# pg_dump --username postgres name_db --file /dir/dir/backup.sql
To restore the database:
First create database with its respective name and roles:
# psql postgres
# postgres=# CREATE DATABASE name_db ENCODING 'UTF-8';
# postgres=# CREATE ROLE
I have a PostgreSQL server running on a remote Debian Squeeze server. I would like to login with the user postgres using the ident and md5 method at the same time. The former is needed for debian maintenance.
I need to compile and install postgresql from source code in a fresh install, no use of apt-get or dpkg and no postgres user created yet.
Compiling and installing is already done, i need those script to start and stop the postgresql service and the creating of postgres user the exactly same way ubuntu does.
This appears to be very messy, so I would like to remove all trace of PostgreSQL on my system. I followed various instructions found on the web, but to no avail. After that, what's the best way to install 9.1?
