[postgis-users] Error upgrading to PostGIS 2.4.3

That error often means there is a dependency missing.


I think I did upgrade some binaries like GDAL and GEOS in last run, so if
you were upgrading while PostGIS lib was in use, you might have gotten an
error like


"Can't overwrite file"  during installation and since 2.4.3 would need the
newer GDAL/GEOS/Proj might fail.  That would cause this problem.  Fix would
be shut down postgresql, restart and rerun the 2.4.3 setup.


Could also be a packaging mistake on my part.


I'll test on my end on a clean 64-bit 9.6.8 to rule out issue on my end.
Last time I had a large number of people complaining about this, it was
because EDB micro upgraded installed a libeasy32.dll that was incompatible
with the curl I was shipping, so I had to recompile the curl to be
compatible with whatever EDB upgraded their SSL libraries to.


Given your 2.3.5 still works?  I assume the ssl is not the issue.

Hi List


Maybe you can point me in the right direction.  I'm running PostgreSQL 9.6.8
(64bit) on Windows 2008 R2 with PostGIS 2.3.5 installed.  I have installed
the 2.4.3 binaries and when I try to run ALTER EXTENSION postgis UPDATE TO
"2.4.3"; I get the following error:


ERROR could not load library PostgreSQL/9.6/lib/postgis-2.4.dll The
specified procedure could not be found.


The file is there.  I've checked permissions and all are valid.  I've
stopped and started the postgresql service.  Am I missing something going
from PostGIS 2.3.x to 2.4.x?  In the past upgrades have been totally


Any help much appreciated.
