Bug#843808: libgdal20: Depends on unwanted packages

[Leandro Guimaraes Faria Corcete DUTRA]

Package: libgdal20
Version: 2.1.2+dfsg-1
Severity: minor
X-Debbugs-CC: Leandro Guimaraes Faria Corcete DUTRA <l at dutras.org>

Dear Maintainer,

I would like to purge the Maria DB libraries from my system, but
libgdal will not let me; if I try, it will cause a request to remove
libgdal and all packages depending on it, including PostGIS which I
want to use with (obviously) PostgreSQL, not Maria.

	Please make all DB drivers, or at least the Maria ones, only
recommendations, not hard dependencies.

	Thanks a lot for your work!
