TimescaleDB-HA Docker image facts

• Image used: timescale/timescaledb-ha:pg16-latest
• PostGIS: Included by default in all (non-oss) tags. The -oss suffix variants ship only OSS-licensed extensions (PostGIS is Apache-licensed, included even in -oss). The GitHub README confirms: "By default, the Docker image contains many extensions, including TimescaleDB and PostGIS."
• -all suffix meaning: Contains multiple Postgres major versions in one image (e.g. pg13+pg14+pg15). NOT about extra extensions. Not needed for TRM.
• PGDATA directory: /pgdata — set via PGDATA=/pgdata env var. NOT the standard /var/lib/postgresql/data. Volume mounts must target /pgdata.
• Environment variables: POSTGRES_USER, POSTGRES_PASSWORD, POSTGRES_DB (same as official postgres image).
• Healthcheck: pg_isready -U $$POSTGRES_USER -d $$POSTGRES_DB (double-in compose YAML to escape interpolation; the container sees single at runtime).
• Compatible with CREATE EXTENSION postgis: Yes, binaries present.
• Compatible with CREATE EXTENSION timescaledb: Yes, it's the whole point of the image.
