After some package update on my Debian (Sid) machine I started to experience errors like:
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)
It mainly happens when I'm trying to perform some queries on Postgres 9.1 database with PostGIS 1.5.
How can I resolve this? Downgrading libc6 and libcstdc++ packages didn't help.
