This is a project for tracking test coverage in PL/PgSQL functions. Very much a work in progress, so things will probably break and/or won't work correctly.
To run, you need to add "pgcov" to shared_preload_libraries. To build on 9.1, you need to do an in-tree build with NO_PGXS=1.
Requires PostgreSQL 9.1 or newer.
