Subject pretty much says it all. Is there a way in a sql query to
have it return the server name and/or the server ip address of the
PostgreSQL server?

thanks,

Chris

8.0 has such informix via functions:

test=> \df *server*
List of functions
Schema | Name | Result data type | Argument data types
------------+------------------+------------------+---------------------
pg_catalog | inet_server_addr | inet |
pg_catalog | inet_server_port | integer |

Depends on the version of PostgreSQL. In 8.0 you can use
inet_server_addr():

http://www.postgresql.org/docs/8.0/s...ions-info.html

Note that inet_server_addr() returns the IP address that you connected
to, so it won't return all IP addresses of a multihomed host. Also,
it will return NULL if you're connected via a local (Unix-domain) socket.

If you're using an earlier version of PostgreSQL, or if you want
more information that the standard functions provide, then you could
write a function in a language like PL/Perl, PL/Tcl, PL/Python, etc.
Example:

CREATE FUNCTION hostname() RETURNS text AS '
use Sys::Hostname;
return hostname;
' LANGUAGE plperlu;
