1. There's a function in the postgres datbase that when executed calls a shared object (dynamically loaded). 2. The shared object is a Client (made using socket library) which connects to a server (coded again using socket library) hosted on some other machine. 3. This server when invoked through the postgres function described above has an ECPG code in it that gets executed after a successful write back to the client, which inserts a record in a table in the postgres database.
I use ECPGdebug in the begening of the server code file to see the state of affairs with the ECPG code and it always raises -402 sqlcode which means the connection attempt to the database did not succeed.
All firewalls in the datbase server and this machine wherein my socket server is running are disabled. Other function calls from this machine to my database machine are working fine.
Also, my postgres function is able to establish connection with the this outside deamon (that i refer to as server coded using socket library). Just the ECPG calls from this deamon back to postgres database are not successful.
