[postgis-devel] About EXTENSION from UNPACKAGED on PostgreSQL 13

[Darafei "Komяpa" Praliaskouski]

Hi,

PostGIS 2.5 had raster and vector blended together in single extension.
In PostGIS 3, they were split out into postgis and postgis_raster extensions.
To upgrade, there is now postgis_extensions_upgrade() function, that
unpackages the raster part out of postgis extensions, upgrades it, and
packages raster functions back into postgis_raster by utilizing FROM
UNPACKAGED.
Removal of FROM UNPACKAGED breaks PostGIS 2.5 -> 3.0 upgrade path, and
we haven't yet found a proper replacement since such removal wasn't
something we were expecting.
