Hello all, I am back with my silly little snippet of code. When I try to create a function with the following code compiled in to an .so: #include <string.h> #include <stdlib.h> #include "postgres.h" #include "fmgr.h" PG_FUNCTION_INFO_V1(ssh_exec); Datum ssh_exec(PG_FUNCTION_ARGS) { char *uname = PG_GETARG_CHAR(0); char *uid = PG_GETARG_CHAR(1); char *gid = PG_GETARG_CHAR(2); char sshcmd[255]; strncpy(sshcmd, "/usr/local/bin/plsshexec ", 255); strncat(sshcmd, VARDATA(uname), VARSIZE(uname)); strncat(sshcmd, " ", 255); strncat(sshcmd, VARDATA(uid), VARSIZE(uid)); strncat(sshcmd, " ", 255); strncat(sshcmd, VARDATA(gid), VARSIZE(gid)); system(sshcmd); return 0; } I get the following error: undefined symbol PG_GETARG_CHAR Is PG_GETARG_CHAR valid? I thought it was. maybe I should re-do it all with PG_GETARG_TEXT. Thanks for reading my post. - Joel
