-# PostGIS Testing in Neon
-
-This directory contains configuration files and patches for running PostGIS tests in the Neon database environment.
-
-## Overview
-
-PostGIS is a spatial database extension for PostgreSQL that adds support for geographic objects. Testing PostGIS compatibility ensures that Neon's modifications to PostgreSQL don't break compatibility with this critical extension.
-
-## PostGIS Versions
-
-- PostgreSQL v17: PostGIS 3.5.0
-- PostgreSQL v14/v15/v16: PostGIS 3.3.3
-
-## Test Configuration
-
-The test setup includes:
-
-- `postgis-no-upgrade-test.patch`: Disables upgrade tests by removing the upgrade test section from regress/runtest.mk
-- `postgis-regular-v16.patch`: Version-specific patch for PostgreSQL v16
-- `postgis-regular-v17.patch`: Version-specific patch for PostgreSQL v17
-- `regular-test.sh`: Script to run PostGIS tests as a regular user
-- `neon-test.sh`: Script to handle version-specific test configurations
-- `raster_outdb_template.sql`: Template for raster tests with explicit file paths
-
-## Excluded Tests
-
-**Important Note:** The test exclusions listed below are specifically for regular-user tests against staging instances. These exclusions are necessary because staging instances run with limited privileges and cannot perform operations requiring superuser access. Docker-compose based tests are not affected by these exclusions.
-
-### Tests Requiring Superuser Permissions
-
-These tests cannot be run as a regular user:
-- `estimatedextent`
-- `regress/core/legacy`
-- `regress/core/typmod`
-- `regress/loader/TestSkipANALYZE`
-- `regress/loader/TestANALYZE`
-
-### Tests Requiring Filesystem Access
-
-These tests need direct filesystem access that is only possible for superusers:
-- `loader/load_outdb`
-
-### Tests with Flaky Results
-
-These tests have assumptions that don't always hold true:
-- `regress/core/computed_columns` - Assumes computed columns always outperform alternatives, which is not consistently true
-
-### Tests Requiring Tunable Parameter Modifications
-
-These tests attempt to modify the `postgis.gdal_enabled_drivers` parameter, which is only accessible to superusers:
-- `raster/test/regress/rt_wkb`
-- `raster/test/regress/rt_addband`
-- `raster/test/regress/rt_setbandpath`
-- `raster/test/regress/rt_fromgdalraster`
-- `raster/test/regress/rt_asgdalraster`
-- `raster/test/regress/rt_astiff`
-- `raster/test/regress/rt_asjpeg`
-- `raster/test/regress/rt_aspng`
-- `raster/test/regress/permitted_gdal_drivers`
-- Loader tests: `BasicOutDB`, `Tiled10x10`, `Tiled10x10Copy`, `Tiled8x8`, `TiledAuto`, `TiledAutoSkipNoData`, `TiledAutoCopyn`
-
-### Topology Tests (v17 only)
-- `populate_topology_layer`
-- `renametopogeometrycolumn`
-
-## Other Modifications
-
-- Binary.sql tests are modified to use explicit file paths
-- Server-side SQL COPY commands (which require superuser privileges) are converted to client-side `\copy` commands
-- Upgrade tests are disabled
