Can't upgrade postgis raster

[robe]

Getting this error on debbie when she tries to upgrade from 2.5.0rc3dev. Seems it's only raster upgrade, postgis upgrade is fine

I assume the reason is raster is part of postgis in 2.5, so we'll definitely need to make accommodations for this in our test script.

Is it run_test.pl trying to CREATE EXTENSION postgis_raster for 2.5.0 ? As it doesn't really make sense to even try ...

It should only happen IF the coming-from version has split raster, as per:

        if ( $OPT_WITH_RASTER && (
                # NOTE: this code is assuming that the default version
                # (!$OPT_UPGRADE_FROM) has split raster extension
                ! $OPT_UPGRADE_FROM ||
                has_split_raster_ext($OPT_UPGRADE_FROM)

The has_split_raster_ext perl subroutine is as follows:

sub has_split_raster_ext
{
  my $fullver = shift;
  my @ver = split(/\./, $fullver);
  return 0 if ( $ver[0] < 2 );
  return 0 if ( $ver[0] == 2 && $ver[1] < 5 );
  return 1;
}

Can you try running that routine in isolation with "2.5.0rc3dev" as input parameter ? It returns 0 here with perl v5.26.1

Sorry, I was mistaken, that subroutine is actually wrong as it thinks split-raster was introduced in 2.5.0 while instead we're adding it in 3.0.0. I'm going to push a fix.

In 16829:

Tell run_test.pl that split-raster was introduced in PostGIS 3.0.0
