Hi, I want to use ctypes to use some functions from postgreSQL server which embeds python interpreter as language pl/python.
That is I want to use ctypes to call _back_ to some internal functions in the server What I tried is the following: hannu=# create or replace function send_raw_notice(rn_text text) returns text language plpythonu as $$ from ctypes import * import struct pg = cdll.LoadLibrary('/usr/lib/postgresql/9.1/bin/postmaster') pg.pq_flush() return rn_text $$; CREATE FUNCTION hannu=# select send_raw_notice('so you see me?'); The connection to the server was lost. Attempting reset: Failed. !> This caused a segfault: 2012-03-31 16:28:24 CEST LOG: server process (PID 8739) was terminated by signal 11: Segmentation fault 2012-03-31 16:28:24 CEST LOG: terminating any other active server processes I suspect it is due to not calling into the host program (the running server) but into a newly loaded and uninitialized copy of postmaster loaded as library Does anyone have ideas how to call into the embedding c program from ctypes ? -------------- Hannu -- http://mail.python.org/mailman/listinfo/python-list
