[postgis-devel] VOTE: Drop PostgreSQL 9.0 support at PostGIS 2.2

[Paragon Corporation]

I think we discussed this but didn't come to an official consensus.

Before we branch to 2.2 in the next couple fo weeks, I'd like to get this
out of the way.

As I have said reasons for dropping

1) Too many PostgreSQL to test and if we ain't going to test it we shouldn't
be saying we support it.
2) Dropping 9.0, all versions left will support extensions which means
getting rid of that conditional extension check.
3) Raster and PostGIS have some legacy code to handle 9.0 in basic postgis
the knn gist operators are not supported in 9.0
In case of raster, Bborie had to put in some logic for 9.0 for the way it
handles aggregates.

It will also make the post-check I'm proposing a tad easier as it would only
do extension testing:
