Huh... It seems that installing the package postgresql-contrib does not
make the work itself.
I provide hereafter a description about how to install the function
connectby (I didn't find such documentation and I don't know where to
write this documentation):
> apt-get install postgresql-contrib-8.1
> emacs /usr/share/postgresql/8.1/contrib/tablefunc.sql
Replace "$libdir" by "/usr/lib/postgresql/8.1/lib/tablefunc.so" (I
suggest to modifying only a copy of this file).
> su postgres
> psql -f /usr/share/postgresql/8.1/contrib/tablefunc.sql <database>
You can check that the work is done as follows:
> psql <database>
<database> => \df connectby
List of functions
Schema | Name | Result data type | Argument data types
--------+-----------+------------------+--------------------------------
-------------
public | connectby | setof record | text, text, text, text, integer
public | connectby | setof record | text, text, text, text,
integer, text
public | connectby | setof record | text, text, text, text, text,
integer, text
I hope that will help another PostgreSQL newbie.
