In trying to set the postgresql admin password in Plesk, I get the following message: PostgreSQL (not supported by your license key) ?? Do I have to buy anything extra to use Postgresql with Plesk? I already have a 300 domain license for Plesk 7 that I'm using. BTW, postgresql-7.3.4-3.rhl9 postgresql-libs-7.3.4-3.rhl9 postgresql-server-7.3.4-3.rhl9 are installed. and postgresql is running.
