# A basic test to ensure Docker images are built correctly.
# Build a wrapper around the compute, start all services and runs a simple SQL query.
# Repeats the process for all currenly supported Postgres versions.

# Implicitly accepts `REPOSITORY` and `TAG` env vars that are passed into the compose file
# Their defaults point at DockerHub `neondatabase/neon:latest` image.`,
# to verify custom image builds (e.g pre-published ones).
#
# A test script for postgres extensions
# Currently supports only v16
