After some package updates on my Debian machine all my database queries involving postgis functions or types are returning:
Error message from server: ERROR: could not load library "/usr/lib/postgresql/9.1/lib/postgis-1.5.so": /lib/x86_64-linux-gnu/libc.so.6: version `GLIBC_2.18' not found (required by /usr/lib/x86_64-linux-gnu/libstdc++.so.6)
Is there a way to resolve this issue? I have to move spatial data between machines, but pg_dump also fails. Is there another way to safely dump my postgis databases?
