[postgis-users] "postgis-3" extension in PostgreSQL extension list of pgAdmin

[Marco Boeringa]

  Hi all,

Having to re-create a database using pgAdmin, I just wondered what the 
"postgis-3" extension represents that is visible in the list of 
suggested extensions in pgAdmin? I have always ignored the entry, and 
chosen "postgis", which seems to work fine, but I have never quite 
understood what the "*-3" post fixed extension objects are (e.g. there 
is also a "postgis_raster-3" visible next the to "postgis_raster" one).

Can someone explain?
