The below listed tarball is out of date at this point, but I have
updated code laying around if someone really wanted it: http://www.joeconway.com/sessfunc.tar.gz
I've used variations of this over the years on several projects.
I've also (mis)used custom configs, e.g. in a plpgsql function:
8<---------------------------- EXECUTE 'set myvars.var1 to ''' || p_var1 || '''';
8<----------------------------
and in your "get session var" C function:
8<----------------------------
#define GET_SESSVAR_BY_NAME(SESS_VAR_NAME) \ do { \ SESS_VAR_NAME = GetConfigOptionByName("myvars."
#SESS_VAR_NAME,\ NULL); \ if (!SESS_VAR_NAME) \
elog(ERROR,"Missing session variable: " #SESS_VAR_NAME); \ } while (0)
char *var1 = GET_SESSVAR_BY_NAME(var1);
