# PostgreSQL 16→18 Upgrade Image for CloudNativePG pg_upgrade
# =============================================================================
# This special image contains BOTH PG16 and PG18 binaries + PostGIS, required
# for CloudNativePG's declarative pg_upgrade feature.
#
# Use this image ONLY for the upgrade process. After upgrade completes,
# switch to the regular cnpg-postgis:18-3.6 image.
#
# Build: docker build --platform linux/arm64 -f Dockerfile.upgrade -t cnpg-postgis:upgrade-16-to-18 .
