Binary Package of PostgreSQL - for dk.kosmisk:postgresql-maven-plugin

This is the artifact for https://github.com/kosmisk-dk/postgresql-maven-plugin. It contains a PostgreSQL binary and a few scripts needed by by the plugin

Content

The package is build by unpacking architecture dependent distribution files from postgresql.org's download page: https://www.enterprisedb.com/download-postgresql-binaries/ And selecting only the needed folders, package them together with scripts to:

  • prepare construct a database with credentials postgres/postgres
  • start start the database and create the given user/database
  • stop shutdown the database

The scripts are given environment variables with the configuration of the database in question.

The variables are:

  • PLUGIN_INSTALL_DIR the directory containing the bin directory of the unpacked postgresql installation
  • PLUGIN_PORT the port the instance is going to listen to
  • PLUGIN_USER the name of the user (not postgres)
  • PLUGIN_PASSWORD the password of the user
  • PLUGIN_DATABASE_NAME the name of the database
  • PLUGIN_DATA_DIR the location of the database content
  • PLUGIN_LOG_FILE the location of the log file

Each of the variables are accompanied by one *_SQL which has the same content as a SQL text ie. PLUGIN_PASSWORD=I'll change it gives PLUGIN_PASSWORD_SQL='I''ll change it'

Besides from this the start script is also given an optional list of sql files as arguments. These files should be loaded in order.

Specific jobs for each command:

  • prepare
    • create a database in ${PLUGIN_DATA_DIR}
    • set up a archive_command that simply removes the archive log
  • start
    • start up the database
    • create a base with name from ${PLUGIN_DATABASE_NAME}
    • create a super user on said base identified by ${PLUGIN_USER}/${PLUGIN_PASSWORD}
    • load all sql files given on command line into said base as said user
  • stop
    • shutdown the database
