PostGIS Raster driver: Crashes in mode 2 with two tiles, side by side (separated by one missing tile)

[pracine]

The driver crashes with this command:

C:\Windows\System32>gdal_translate -oF GTiff "PG:host='localhost' dbname='test3' user='postgres' password='1postgres' ta
ble='test03_2' mode=2" c:/temp/test03_2-mode2.tif

on a table like this:

CREATE TABLE test03_2 AS
SELECT 1 rid, ST_MapAlgebraExpr(ST_AddBand(ST_MakeEmptyRaster(10, 10, 0, 0, 0.1, 0.1, 0, 0, 4269), '8BUI'::text, 1, 0), '32BUI', '([rast.x] - 1) * 10 + [rast.y]') rast
UNION ALL
SELECT 2 rid, ST_MapAlgebraExpr(ST_AddBand(ST_MakeEmptyRaster(10, 10, 2, 0, 0.1, 0.1, 0, 0, 4269), '8BUI'::text, 1, 0), '32BUI', '([rast.x] - 1) * 10 + [rast.y] + 1') rast;

It also crashes with this raster arrangement which should be just a little bit more complex to handle:

CREATE TABLE test04 AS
SELECT 1 rid, ST_MapAlgebraExpr(ST_AddBand(ST_MakeEmptyRaster(10, 10, 0, 0, 0.1, 0.1, 0, 0, 4269), '8BUI'::text, 1, 0), '32BUI', '([rast.x] - 1) * 10 + [rast.y]') rast
UNION ALL
SELECT 2 rid, ST_MapAlgebraExpr(ST_AddBand(ST_MakeEmptyRaster(10, 10, 1, 1, 0.1, 0.1, 0, 0, 4269), '8BUI'::text, 1, 0), '32BUI', '([rast.x] - 1) * 10 + [rast.y] + 1') rast;

All those tickets have more than one year and nobody has acted on it, so the priority is not so high
