You got a PostgreSQL server running somewhere?

It needs to be able to access the cocanwiki database while compiling
(see extensive documentation for PG'OCaml on this subject for why).

It'll connect to a local database automatically, but otherwise you'll
need to set the $PGHOST etc. variables (see psql manpage).
