xTuple Admin Guide

Make sure the postgresql.conf file in your database server's data directory contains the following lines if you're running PostgreSQL 9.1 on Mac or Linux (NOTE: PostgreSQL 9.1 is not currently supported on Windows):

custom_variable_classes = 'plv8'
plv8.start_proc = 'xt.js_init'

If you are running PostgreSQL 9.2.0 and later, only include the following line:

plv8.start_proc = 'xt.js_init'

You can put those lines anywhere in the postgresql.conf file you want but it's safest to put them at the end. If there's already a custom_variable_classes line with something between the single-quotes, add ,plv8 to the line inside the quotes. You can check if plv8.start_proc is there already by querying the database server in psql or pgAdmin:

psql> show plv8.start_proc;
