Pagila

Pagila is a port of the Sakila example database available for MySQL, which was originally developed by Mike Hillyer of the MySQL AB documentation team. It is intended to provide a standard schema that can be used for examples in books, tutorials, articles, samples, etc.

Pagila works against PostgreSQL 11 and above.

All the tables, data, views, and functions have been ported; some of the changes made were:

  • Changed char(1) true/false fields to true boolean fields
  • The last_update columns were set with triggers to update them
  • Added foreign keys
  • Removed 'DEFAULT 0' on foreign keys since it's pointless with real FK's
  • Used PostgreSQL built-in fulltext searching for fulltext index. Removed the need for the film_text table.
  • The rewards_report function was ported to a simple SRF

The schema and data for the Sakila database were made available under the BSD license which can be found at http://www.opensource.org/licenses/bsd-license.php. The pagila database is made available under this license as well.

FULLTEXT SEARCH

Fulltext functionality is built in PostgreSQL, so parts of the schema exist in the main schema file.

Example usage:

SELECT * FROM film WHERE fulltext @@ to_tsquery('fate&india');

PARTITIONED TABLES

The payment table is designed as a partitioned table with a 6 month timespan for the date ranges. If you want to take full advantage of table partitioning, you need to make sure constraint_exclusion is turned on in your database. You can do this by setting "constraint_exclusion = on" in your postgresql.conf, or by issuing the command "ALTER DATABASE pagila SET constraint_exclusion = on" (substitute pagila for your database name if installing into a database with a different name)

INSTALL NOTE

The pagila-data.sql file and the pagila-insert-data.sql both contain the same data, the former using COPY commands, the latter using INSERT commands, so you only need to install one of them. Both formats are provided for those who have trouble using one version or another.

CREATE DATABASE ON DOCKER

  1. On terminal pull the latest postgres image:
 docker pull postgres
  1. Run image:
 docker run --name postgres -e POSTGRES_PASSWORD=secret -d postgres
  1. Run postgres and create the database:
docker exec -it postgres psql -U postgres

psql (13.1 (Debian 13.1-1.pgdg100+1))
Type "help" for help.

postgres=# CREATE DATABASE pagila;
postgres-# CREATE DATABASE
postgres=\q
  1. Create all schema objetcs (tables, etc) replace <local-repo> by your local directory :
cat <local-repo>/pagila-schema.sql | docker exec -i postgres psql -U postgres -d pagila
  1. Insert all data:
cat <local-repo>/pagila-data.sql | docker exec -i postgres psql -U postgres -d pagila
  1. Done! Just use:
docker exec -it postgres psql -U postgres

postgres
psql (13.1 (Debian 13.1-1.pgdg100+1))
Type "help" for help.

postgres=# \c pagila
You are now connected to database "pagila" as user "postgres".
