Description: Bug with Pl/Python
Details:

I'm trying run this command:
=# CREATE LANGUAGE "plpythonu"

But it only throws a SIGABRT
I set all debug levels to the maximum (debug5), and I was compiled with the
option --enable-debug, when I run "gdb /postgresql-bin/postgres"
...
run -D path-database template1
...
postgres> CREATE LANG "plpythonu";
LOCATION: elog_node_display, print.c:86
STATEMENT: create language "plpythonu"

DEBUG: 00000: ProcessUtility
LOCATION: PortalRunUtility, pquery.c:952
STATEMENT: create language "plpythonu"

Program received signal SIGABRT, Aborted.
[Switching to LWP 1]
0x0000000201d2d15e in kill () from /usr/lib/libc.so.12
(gdb) backtrace
#0 0x0000000201d2d15e in kill () from /usr/lib/libc.so.12

Reading this, I can't found where is the problem, could this be a bug?
