Hi

i installed the openemr but when i navigate to billing tab i am getting following error

Fatal error: Call to undefined function: pg_pconnect() in /www/openemr/library/sql-ledger.inc on line 11

i installed sql-ledger and PostgreSQL sql in my system

How to overcome above error did i miss any configuration for sql-ledger or PostgreSQL

Thanks
Kumar
