[postgis-users] 'postgis.backend' is already set

Hi all !

After upgrading to Postgis 2.2 (from 2.1.3 I believe), my server log is
filled with these messages :

"WARNING 'postgis.backend' is already set and cannot be changed until
you reconnect"

I have read some discussions about this message and the closed trac
ticket as well, but they all concern upgrade problems (i.e. upgrade
fails because of this message).
In my case the upgrade did not fail and my PostGIS runs perfectly fine,
appart from this message.
Is it a symptom that something is going bad on my server ? How can I get
rid of it ?

OS : Windows Server 2013 64 bits
PostGreSQL : PostgreSQL 9.5.3, compiled by Visual C++ build 1800, 64-bit
PostGIS (installed via stack builder) : POSTGIS="2.3.2 r15302"
GEOS="3.6.1-CAPI-1.10.1 r4317" PROJ="Rel. 4.9.1, 04 March 2015"
GDAL="GDAL 2.1.3, released 2017/20/01" LIBXML="2.7.8" LIBJSON="0.12" RASTER

Thanks !
