alpine-postgre

PostgreSQL Docker container based on Alpine Linux and with the same API as official container has.

Whats different?

1. Added POSTGRES_LOG_STATEMENTS environment variable that helps with settings custom verbosity for statements log.
2. Added REPLICATOR_USER (default: phhoard) and REPLICATOR_PASSWORD environment variables that will allow replication connections to a running container. (By default PostgreSQL all statement does not include replication in pg_hba.conf.)
3. Improved entrypoint script to support backups from restored PostgeSQL data directory.

How to restore from backup?

Place your restored PGDATA to ${PGDATA}/../restored_data (by default: var/lib/postgresql/restored_data) and restart the container. During restart it will:

1. Move current PGDATA to ${PGDATA}/../corrupted_data. (You will need to remove it manually later.)
2. Move files from restored_data to $PGDATA.
3. Remove restored_data directory.
