-# 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

+// A GetPage request contains two LSN values:
+//
+// request_lsn: Get the page version at this point in time.  Lsn::Max is a special value that means
+// "get the latest version present". It's used by the primary server, which knows that no one else
+// is writing WAL. 'not_modified_since' must be set to a proper value even if request_lsn is
+// Lsn::Max. Standby servers use the current replay LSN as the request LSN.
+//
+// not_modified_since: Hint to the pageserver that the client knows that the page has not been
+// modified between 'not_modified_since' and the request LSN. It's always correct to set
+// 'not_modified_since equal' to 'request_lsn' (unless Lsn::Max is used as the 'request_lsn'), but
+// passing an earlier LSN can speed up the request, by allowing the pageserver to process the
+// request without waiting for 'request_lsn' to arrive.
+//
+// The now-defunct V1 interface contained only one LSN, and a boolean 'latest' flag. The V1 interface was
+// sufficient for the primary; the 'lsn' was equivalent to the 'not_modified_since' value, and
+// 'latest' was set to true. The V2 interface was added because there was no correct way for a
+// standby to request a page at a particular non-latest LSN, and also include the
+// 'not_modified_since' hint. That led to an awkward choice of either using an old LSN in the
+// request, if the standby knows that the page hasn't been modified since, and risk getting an error
+// if that LSN has fallen behind the GC horizon, or requesting the current replay LSN, which could
+// require the pageserver unnecessarily to wait for the WAL to arrive up to that point. The new V2
+// interface allows sending both LSNs, and let the pageserver do the right thing. There was no
+// difference in the responses between V1 and V2.
+//
+// V3 version of protocol adds request ID to all requests. This request ID is also included in response
+// as well as other fields from requests, which allows to verify that we receive response for our request.
+// We copy fields from request to response to make checking more reliable: request ID is formed from process ID
+// and local counter, so in principle there can be duplicated requests IDs if process PID is reused.

-// A GetPage request contains two LSN values:
-//
-// request_lsn: Get the page version at this point in time.  Lsn::Max is a special value that means
-// "get the latest version present". It's used by the primary server, which knows that no one else
-// is writing WAL. 'not_modified_since' must be set to a proper value even if request_lsn is
-// Lsn::Max. Standby servers use the current replay LSN as the request LSN.
-//
-// not_modified_since: Hint to the pageserver that the client knows that the page has not been
-// modified between 'not_modified_since' and the request LSN. It's always correct to set
-// 'not_modified_since equal' to 'request_lsn' (unless Lsn::Max is used as the 'request_lsn'), but
-// passing an earlier LSN can speed up the request, by allowing the pageserver to process the
-// request without waiting for 'request_lsn' to arrive.
-//
-// The now-defunct V1 interface contained only one LSN, and a boolean 'latest' flag. The V1 interface was
-// sufficient for the primary; the 'lsn' was equivalent to the 'not_modified_since' value, and
-// 'latest' was set to true. The V2 interface was added because there was no correct way for a
-// standby to request a page at a particular non-latest LSN, and also include the
-// 'not_modified_since' hint. That led to an awkward choice of either using an old LSN in the
-// request, if the standby knows that the page hasn't been modified since, and risk getting an error
-// if that LSN has fallen behind the GC horizon, or requesting the current replay LSN, which could
-// require the pageserver unnecessarily to wait for the WAL to arrive up to that point. The new V2
-// interface allows sending both LSNs, and let the pageserver do the right thing. There was no
-// difference in the responses between V1 and V2.
-//
-// V3 version of protocol adds request ID to all requests. This request ID is also included in response
-// as well as other fields from requests, which allows to verify that we receive response for our request.
-// We copy fields from request to response to make checking more reliable: request ID is formed from process ID
-// and local counter, so in principle there can be duplicated requests IDs if process PID is reused.
