This signature detects attempts to exploit a known vulnerability against PostgreSQL. A successful attack can lead to arbitrary code execution.
The Database Link library (dblink) in PostgreSQL 8.1 implements functions via CREATE statements that map to arbitrary libraries based on the C programming language, which allows remote authenticated superusers to map and execute a function from any library, as demonstrated by using the system function in libc.so.6 to gain shell access.
