Re: BUG #16628: Hostame and string connection functions
I'm sorry for not responding earlier. She ended up falling into spam. I solved it by creating a specific variable in the postgresql configuration file.
If it's not too much trouble, I have another question: my name is Anderson Antunes. I live in Brazil. I'm doing research for a master's project about pseudo random numbers and would like to know more information about the random() function used to randomly order a set of records. I tried to search through the site that offers the source code but I couldn't identify the exact implementation of this function.
Can you help me?

You can get the server IP address, but not the host name:
test=> SELECT inet_server_addr();
inet_server_addr
------------------
127.0.0.1
> select get_string_connection ();
Uh, the connection information is parsed by libpq, and visible in psql:
test=> \conninfo You are connected to database "test" as user
"postgres" on host "localhost" (address "127.0.0.1")
at port "5432".
but the server only sees the result. You can see the server port
number:
test=> SELECT inet_server_port();
inet_server_port
------------------
5432
I can't figure out how to query the SSL mode via SQL. Does this help?
