Re: creating a function in psql

Hi
I've just done the very same thing today and found how to add plpgsql
into the pg_languages.
Firstly I located where plpgsql was on our server.
In that directory there was a file called install which gives
instructions using make file and then adding the language to your
pg_language table.
It also gives instructions on how to add it to the template1 so all
created databases will include the language.
I found that I didn't need to use makefile and was able to just do the
psql dbname <mklang.sql

This was the instruction and location of our plpgsql:-

psql test
</usr/ports/databases/postgresql/work/postgresql-6.5.2/src/pl/plpgsql/src/mklang.sql

Once this is created successfully, then you can write the functions
using plpgsql.

Hope this helps

Regards,
Julie
