# Postgresql docker image

[![build multirach postgresql Docker image and push to it dockerhub](https://github.com/openremote/postgresql/actions/workflows/postgresql.yml/badge.svg)](https://github.com/openremote/postgresql/actions/workflows/postgresql.yml)

 POSTGIS and TimescaleDB (inc. toolkit for hyperfunctions) image built for aarch64 support using `timescaledev/timescaledb-ha` base image with:

- OR specific ENV variables and a healthcheck added

- Easy configuration of `max_connections` using `POSTGRES_MAX_CONNECTIONS` environment variable (set to `-1` to disable this setting)

- PGDATA path set to match old Alpine image (for ease of DB migration)

- POSTGRES user UID and GID changed to match old Alpine image (for ease of DB migration)

- Auto upgrade of database with PG major version changes from previous PG major version; can be disabled using

  OR_DISABLE_AUTO_UPGRADE=true.

- Auto upgrade of timescaleDB extension when a new version is available in the container; can be disabled using

  OR_DISABLE_AUTO_UPGRADE=true.

- OR_DISABLE_REINDEX env variable with associated scripts to determine if a REINDEX of the entire DB should be carried

  out at first startup with existing DB (checks whether or not $PGDATA/OR_REINDEX_COUNTER.$OR_REINDEX_COUNTER exists).

  This is used when a collation change has occurred (glibc version change, muslc <-> glibc) which can break the indexes;

  migration can either be manually handled or auto handled depending on OR_DISABLE_REINDEX env variable value.

  NOTE THAT A REINDEX CAN TAKE A LONG TIME DEPENDING ON THE SIZE OF THE DB! And startup will be delayed until completed

  This functionality is intended to simplify migration for basic users; advanced users with large DBs should take care of this

  themselves.

`timescale/timescaledb-ha` image is ubuntu based and only currently supports amd64; they are working on ARM64 support in timescaledev/timescaledb-ha see:

https://github.com/timescale/timescaledb-docker-ha/pull/355

See this issue for POSTGIS base image aarch64 support discussion:

https://github.com/postgis/docker-postgis/issues/216

TODO: Switch over to timescale/timescaledb-ha once arm64 supported

## Upgrading

***NOTE: If you change the version of container you use then make sure you have backed up your DB first as this container will try to auto upgrade your DB and/or TimescaleDB extension; this auto upgrade functionality can be disabled using `OR_DISABLE_AUTO_UPGRADE=true`***
