问题
I'm trying to get my dev environment back up and running after upgrading to Snow Leopard. In particular, I need postgresql and postgis working, but I'm running into the following problem.
After installing both with the following:
sudo port install postgresql84 postgresql84-server postgis
I get errors like the following when I try to load my sql database, which has references to liblwgeom.so
ERROR: function public.box3d_in(cstring) does not exist
ERROR: incompatible library "/usr/local/pgsql/lib/liblwgeom.so": version mismatch
DETAIL: Server is version 8.4, library is version 8.3.
That file does exist on my computer, but must be sitting around from an old install of postgresql 8.3. The problem is I can't figure out where liblwgeom.so is supposed to come from. It's not included in postgis 1.4, and a Google search is leaving me scratching my head. Any ideas?
回答1:
liblwgeom.so comes with PostGIS vesion 1.3. It has been renamed in 1.4. It looks like your dump is of a database with PostGIS 1.3 and you're trying to reload in PostGIS 1.4. This is not supported.
See the PostGIS manual on upgrading for details on what to do.
回答2:
Update your ports:
sudo port selfupdate
Then install postgis 1.4, which will work for postgresql 8.4
sudo port install postgis
