Migrate Db To Postgres
Migrating a SQLite database to PostgreSQL¶ This command instructs pgloader to load data from a SQLite file. Automatic discovery of the schema is supported, including build of the indexes. You can use pgdump to extract a PostgreSQL database into a script file and psql to import the data into the target database from that file. To step through this how-to guide, you need: An Azure Database for PostgreSQL server with firewall rules to allow access and database under it.
Are you planning to free yourself from Oracle license fees or are you playing with the idea of leaving Oracle behind? Then Cybertec Schönig & Schönig GmbH will be the right partner for you. Our team of PostgreSQL and Oracle experts offer a smooth transition from the commercial to the Open Source world.
Our team is not only made up of PostgreSQL experts – we also have Oracle certified staff with considerable Oracle database experience. We are able to fully comprehend the Oracle side of the migration project.
Why move from Oracle to PostgreSQL
Moving to PostgreSQL ensures:
- Reduction of license costs to ZERO
- Reduction of support costs by 80% or more
- Substantial reduction of training + consulting costs
Cybertec Cybertec & Schönig & Schönig GmbH will migrate customers to the Open Source version of PostgreSQL to free you completely from any kind of vendor lock. There is no “special closed source version” and no proprietary tool chain. After migrating to PostgreSQL, you will be running on an Open Source solution (100%, no strings attached).
PostgreSQL license costs will be ZERO.
Our goal is to make your PostgreSQL deployment at least as fast as your current Oracle setup. However, the total cost of operating your database infrastructure will drop considerably. Reduced costs will apply to all aspects of your deployment including ongoing operations, maintenance, etc.
Database stability and data security
Primary concerns brought up by many who have already moved from Oracle to PostgreSQL are the questions of security, stability, and quality.
We can assure you that PostgreSQL is a rock solid database, which has been repeatedly proven over the years. It has been adopted in critical environments such as banking, government, defense, medicine, and in the automotive industry (to mention just a few).
Our very existence depends on PostgreSQL’s quality.
Our team here at Cybertec Schönig & Schönig GmbH and the entire PostgreSQL industry depends on the quality and stability of the PostgreSQL code base, which means that everybody is working hard to maintain good quality, superior stability, and high standards of development.
Remember: It is not only your data, which is at stake – the same applies to our reputation and the existence of the entire industry, which will do everything to protect your data by every possible means available.
Make use of our migration toolchain
Cybertec uses an Open Source tool chain as well as a couple of own scripts (available as Open Source to customers) to move customers from Oracle to PostgreSQL.
Some of the tools we use are:
- oracle_fdw: Ideal to move schemas and data
- ora2pg: Ideal for large migration projects
- orafce: Compatibility functions
The entire migration process is fully transparent. Cybertec will also make sure that Oracle PL/SQL code is properly adapted and optimized for PostgreSQL.
Contact usOracle is not only a classical database. It also features an extension to handle GIS data, which is used by some players in the industry. On the PostgreSQL side there is also an extension to handle GIS data. PostGIS is an enterprise ready GIS framework, which has constantly been developed over the years.
GIS data is not quite like normal data. It sometimes requires some special treatment and well as special indexing.
If you are using Oracle Spatial we can help with migration.

You don't need to create an intermediate file. You can do
or
using psql or pg_dump to connect to a remote host.
With a big database or a slow connection, dumping a file and transfering the file compressed may be faster.
As Kornel said there is no need to dump to a intermediate file, if you want to work compressed you can use a compressed tunnel
or
but this solution also requires to get a session in both ends.
the Tin ManThen copy the backup to your development server, restore with:
unmountedunmountedUse pg_dump, and later psql or pg_restore - depending whether you choose -Fp or -Fc options to pg_dump.
Example of usage:
If you are looking to migrate between versions (eg you updated postgres and have 9.1 running on localhost:5432 and 9.3 running on localhost:5434) you can run:

pg_basebackup seems to be the better way of doing this now, especially for large databases.
Run this command with database name, you want to backup, to take dump of DB.
Now scp this dump file to remote machine where you want to copy DB.
On remote machine run following command in ~/some/folder to restore the DB.
I struggled quite a lot and eventually the method that allowed me to make it work with Rails 4 was:
on your old server
I had to use the postgres linux user to create the dump. also i had to use -c to force the creation of the database on the new server. --inserts tells it to use the INSERT() syntax which otherwise would not work for me :(
then, on the new server, simpy:
to transfer the dump.sql file between server I simply used the 'cat' to print the content and than 'nano' to recreate it copypasting the content.
Also, the ROLE i was using on the two database was different so i had to find-replace all the owner name in the dump.
pastullopastulloLet me share a Linux shell script to copy your table data from one server to another PostgreSQL server.
Linux Bash Shell Script for data migration between PostgreSQL Servers:
I am just migrating the data; please create a blank table at your destination/second database server.
This is a utility script. Further, you can modify the script for generic use something like by adding parameters for host_name, database_name, table_name and others

Dump your database : pg_dump database_name_name > backup.sql
Import your database back: psql db_name < backup.sql
