Forum OpenACS Q&A: static-pages doesn't load data model

I was going to report it in the SDM, but since I downloaded the 4.5 version and got the same error, I wonder what is wrong.
on PG 7.2, AOLserver 3.4.2, when loading the data model I get:

couldn't execute "psql": no such file or directory
    while executing

I do not understand the error.

Jeff,

The system is running, so it is already using PG.

Since I have PG7.1 for and older site, and I am now using 7.2 to test ACS 4.6, I put PG7.2 in ad different port.

I set up the nsd-conf files

set pgport              5433
ns_param  pgport            $pgport

and

ns_param  datasource        localhost:${pgport}:${db_name}

for each of the DB pools.

Could it be that there is a call in the RP or somewhere else? that doesn't use the pgport parameter?

Thanks
