PostgreSQL for Linux Payload Execution

Description

On some default Linux installations of PostgreSQL, the
postgres service account may write to the /tmp directory, and
may source UDF Shared Libraries from there as well, allowing
execution of arbitrary code.

This module compiles a Linux shared object file, uploads it to
the target host via the UPDATE pg_largeobject method of binary
injection, and creates a UDF (user defined function) from that
shared object. Because the payload is run as the shared object's
constructor, it does not need to conform to specific Postgres
API versions.
