I'm a relative newbie to Postgres but I've asked a few colleagues about this problem without a solution, so I'm hoping someone on the list serve can help.
The problem arose when I move to an upgraded operating system, an upgraded version of Postgres, and when I dump a database out of the old machine and restore it on a new machine.
Old: RedHat 5.9, Postgres 8.1.23
New: RedHat 6.6, Postgres 9.2
Everything worked fine with the old setup. With the new setup, I can access my database through psql command-line. However, I have a compiled program called 'Shefdecode' that makes queries to the database through ECPG and this program cannot access the database. I get errors:
"Postgres error -220" and
"SQL STATE = 08003" (User manual says this means "The program tried to access a connection that does not exist.")
Although I don't have the source for the Shefdecode program, I know it uses the environment variables PGUSER and PGHOST and also gets passed the database name. I've checked to make sure these are correct.
What else should I look for to try to determine the cause of this error?
Any ideas would be greatly appreciated.
