PostGIS Docker image with pg_plan_filter

This repo just contains a Dockerfile to build a PostgreSQL Docker image with PostGIS and pg_plan_filter, as well as a GitHub Actions CI config to automatically publish it.

Note: The pg_plan_filter project does not provide a .control file & .sql initialization script, so we add it manually, so that pg_plan_filter can then be loaded using CREATE EXTENSION plan_filter.
